Disk-Space Requirements for Internet Explorer 5.01 Installation
---------------------------------------------------------------
Internet Explorer 5.01 and Internet Tools Setup installs the 
majority of its files to the drive where the Windows operating 
system is installed, regardless of the installation location you 
chose. To free up space on your hard disk in order to meet the 
Internet Explorer 5.01 disk-space installation requirements, 
you must free up space on the drive where the Windows operating 
system is installed.

Installing Windows NT 4.0 Service Pack 4
----------------------------------------
After you install Windows NT 4.0 Service Pack 4 but before you 
install Internet Explorer 5.01, you may see a message recommend-
ing that you install one or both of the following Service Packs 
to resolve known Year 2000 issues:

  - Internet Explorer 4.01 Service Pack 1
  - Microsoft Data Access Components 2.0 Service Pack 1

Internet Explorer 5.01 resolves the Year 2000 issues addressed in 
these Service Packs.


SETUP
=====

Installing Internet Explorer 5.01 and Internet Tools
----------------------------------------------------
Whether you choose to install over the network or download the 
installation files to your hard disk, some or all of the Setup 
files are copied to your hard disk. This allows you to reinstall 
more quickly if necessary. If you want to reclaim the disk space, 
you can remove the Setup directory by double-clicking the 
Add/Remove Programs icon in Control Panel and then clicking 
Internet Explorer 5.01. In the Microsoft Internet Explorer Setup 
dialog box, click the Advanced button, and then click "Remove the 
folder containing Internet Explorer setup files."

You cannot install Internet Explorer 5.01 to or run it from a 
network drive. However, you can download it to a network drive. 
To do this, you must map the network drive to a drive letter on 
your computer. You cannot download Internet Explorer 5.01 to a 
UNC path.

Running Internet Explorer 5.01 on Microsoft Windows NT 4.0
----------------------------------------------------------
NOTE: You must have administrative privileges to install 
      and uninstall this program on Windows NT. This includes 
      having administrative privileges the first time you 
      start your computer after installing or uninstalling.

You must restart your computer after installing Internet 
Explorer 5.01. This is also true for some add-on components.

For corporate deployment on computers running Windows NT 4.0, 
make sure you have the following free registry space:

  - If you are upgrading from Internet Explorer 2.0 or 
    Internet Explorer 3.x: at least 4 MB
  - If you are upgrading from Internet Explorer 4.x:
    at least 2.5 MB 

If you're running Internet Explorer 5.01 on Windows NT 4.0, 
you must set user permissions to Full Control for the Temporary 
Internet Files folder (cache). The user must have write 
permission so that files can be stored in the Temporary 
Internet Files folder.

If you must reinstall Windows NT 4.0 Service Pack 3 (SP3) 
after you install Internet Explorer 5.01, you must specify 
when prompted that you do not want it to overwrite any files 
that are newer. After SP3 is reinstalled, carry out the 
following steps to update the registry:

1. Click the Start button, and then click Run.
2. Type the following: regsvr32 rsabase.dll
3. Click OK.

Installing Windows NT 4.0 Service Packs 
Over Internet Explorer 5.01
---------------------------------------
If you reinstall a Windows NT 4.0 Service Pack after Internet 
Explorer 5.01 is installed on your computer, some components 
will need to be re-registered. To do this, carry out the 
following steps:

1. In Control Panel, double-click Add/Remove Programs.
2. Click the Install/Uninstall tab.
3. Click Microsoft Internet Explorer 5.01 and Internet Tools, 
   and then click the Add/Remove button.
4. Click Repair Internet Explorer, and then click OK.
5. After the repair operation is complete, restart your computer.

Installing Over Windows 2000 Releases
-------------------------------------
This is not a supported configuration. Setup will appear to run, 
but it will update the name of the browser without updating the 
components. You cannot do a full installation of Microsoft 
Internet Explorer 5.01 components over Windows 2000 releases. 

Running Internet Explorer 5.01 on a Dual-Boot Operating System
--------------------------------------------------------------
If you are running Internet Explorer 5.01 on a computer that is
set up to dual boot between two operating systems on the same 
partition (for example, Windows 95 and Windows NT 4.0), and you 
have configured the computer to share a single Program Files 
folder, you may have problems with add-on components. Also, when 
you uninstall an add-on component from either copy of Internet 
Explorer 5.01, it will be removed from both of them without 
updating the other operating system's installed components 
information. These problems are because the add-on files are 
all stored in the shared Program Files folder, but information 
about installed add-on components is stored elsewhere.

Installing or Upgrading the Windows Desktop Update
--------------------------------------------------
To install or upgrade the Windows Desktop Update, you must 
install Internet Explorer 4.01 SP2 before you install 
Internet Explorer 5.01. 

If you have already installed Internet Explorer 5.01 and would 
like to install the Windows Desktop Update, carry out the 
following steps:

1. Uninstall Internet Explorer 5.01.
2. If Internet Explorer 4.01 SP2 is not already installed on 
   your computer, install it.
3. Install the Windows Desktop Update.
4. Reinstall Internet Explorer 5.01.

Installing Over Localized Windows 98 Arabic and Hebrew Releases
---------------------------------------------------------------
Windows 98 Arabic and Hebrew require the corresponding localized 
version of Internet Explorer 5.01. It is not possible to install 
the English version of Internet Explorer over the localized 
version of Windows 98. This restriction does not apply to 
localized versions of Windows 95 or Windows NT 4.0. You cannot 
install localized Arabic/Hebrew Internet Explorer 5.01 on top of 
localized Windows 95 (only English is supported). 

Installing Outlook Express 5 on Windows Terminal Server
-------------------------------------------------------
Before installing Outlook Express 5 on Windows Terminal 
Server, the administrator needs to set a compatibility flag 
in the registry for the Outlook Express 5 setup program to 
work correctly. To do this, carry out the following steps:

1. Create this registry key:

   HKEY_LOCAL_MACHINE\Microsoft\Windows NT\CurrentVersion\
   Terminal Server\Compatibility\Applications\setup50

2. Set the following value under the new setup50 key (this value 
   should be of type REG_DWORD): 

   Flags = 0x108

Installing Internet Explorer 5.01 
with Norton Protected Recycle Bin Enabled
-----------------------------------------
It is recommended that you disable the Norton Protected 
Recycle Bin while you install Internet Explorer 5.01, and 
that you empty the Norton Protected Recycle Bin before you 
run Setup. Before you empty the Norton Protected Recycle 
Bin, be sure you review its contents in case it contains 
any items you want to recover safely. You can re-enable 
this feature after Internet Explorer 5 Setup is complete.

This is recommended because Norton Protected Recycle Bin 
will intercept the removal of temporary files that Setup 
is trying to delete, and you could run out of free space 
on your hard disk if your remaining free space is limited. 
This would cause Internet Explorer Setup to appear locked. 
For instructions on disabling and re-enabling the Norton 
Protected Recycle Bin, see the Norton Utilities documentation.

Installing on Windows 98 with Novell IPX/IP client
--------------------------------------------------
If you are using Novell IPX/IP client with Windows 98, you may 
experience problems if you install Internet Explorer 5.01 from 
the Internet. If Setup appears to become unresponsive, restart 
your computer. Setup will continue and finish normally. To work 
around this problem, try one of the following options:

- From the Internet, select the Download Only option, 
  and then run and install Internet Explorer 5.01 normally.

- Install Internet Explorer 5.01 from a CD-ROM.

Uninstalling Internet Explorer 5.01 and Internet Tools
------------------------------------------------------
You can uninstall Internet Explorer 5.01 and Internet Tools by 
carrying out the following steps:

1. In Control Panel, double-click the Add/Remove Programs icon.
2. Click Microsoft Internet Explorer 5.01 and Internet Tools, 
   and then click Add/Remove.
3. Select "Restore the previous Windows configuration," then 
   click OK.
4. Follow the instructions on your screen.

Uninstall for Internet Explorer 4.x Unavailable
-----------------------------------------------
Uninstall for Internet Explorer 4.x is unavailable when Internet 
Explorer 5.01 is installed. The backup files for uninstalling 
Version 4.x are replaced by the backup files for version 5. 
You cannot uninstall version 4.X after uninstalling version 5.


ADDITIONAL ISSUES
=================

Work Offline Dialog Box Appears 
If There Is No Internet Connection
----------------------------------
If you do not have an active connection to the Internet and 
the Never Dial A Connection option is selected, when you start 
Internet Explorer you may see the following error message: 
"Web page not available when offline." You will be prompted to 
try again or work offline.

To be prompted to dial a connection:

1. On the Tools menu, click Internet Options.
2. Click the Connections tab.
3. Click one of the following options:
   Dial Whenever A Network Connection Is Not Present
   - or -
   Always Dial My Default Connection
4. Click OK or Apply.

FTP User Interface and Functionality
------------------------------------
Internet Explorer 5.01 has an improved FTP user interface 
when direct access to an FTP server is available. If you 
discover an issue in the FTP user interface that blocks FTP 
functionality, you can disable this feature on the Advanced 
tab in the Internet Options dialog box.
 
The following functionality is not supported:
 
- Internet connection via CERN proxy or Web proxies.
- Connecting to VAX or VMS FTP servers.
- Using the browser from within a separate application or 
  service.
- Copying from server to server.
- Drag and drop or copy/paste functionality from an FTP 
  server is supported only on Windows 2000 and later.

Font Display Issues
-------------------
If you run a non-Far East language version of Windows NT 4.0 
and you have installed many large fonts, the system's ability 
to use those fonts may be exceeded. If Far East language Web 
pages are not displayed correctly, install Windows NT 4.0 Service 
Pack 5.

Non-English Characters in URLs and Queries
------------------------------------------
Internet Explorer 5.01 uses a new standard to transmit non-
English addresses (URLs) to the server. URLs are now encoded 
in a character encoding standard named UTF-8. If the server is 
running Microsoft Internet Information Server 4 or later, the 
URLs will work as expected. Many servers cannot process URLs 
encoded in UTF-8. To use non-English characters in URLs with 
these servers, carry out the following steps:
 
1. On the Tools menu, click Internet Options.
2. Click the Advanced tab.
3. Clear the Always Send URLs As UTF-8 check box.
 
The query part of URLs is transmitted in a form fully compatible 
with Internet Explorer 4.

Internet Explorer 4.x Compatibility Mode
----------------------------------------
The Internet Explorer 4.x compatibility option is useful to 
Web developers who want to view and test their Web sites on 
different versions of Internet Explorer using the same computer. 
You may not be able to change all settings for the browser while 
in this mode. When using the compatibility option, you should 
change Internet Options through Control Panel, not through the 
browser's Internet Options on the Tools menu.

Uninstalling Outlook Express 5 
------------------------------ 
If you uninstall Outlook Express 5 and you were previously 
running Internet Mail and News, you would be able to see only 
the messages you received using Internet Mail and News. To 
view Outlook Express 5 messages, reinstall Outlook Express 5. 
 
If you uninstall Outlook Express 5 and you were previously 
running Outlook Express 4, you can view your Outlook Express 5 
messages by using the Import feature. To import your Outlook 
Express messages to Outlook Express 4, carry out the following 
steps:

1. On the File menu, click Import, and then click Messages.
2. On the list of programs, click Microsoft Outlook Express 5.
3. Follow the instructions on your screen.

Windows Radio Toolbar
---------------------
Internet Explorer 5.01 includes a Windows Radio toolbar that 
allows streaming radio playback. By default, the toolbar is 
not displayed when the browser is started. To display the 
toolbar whenever the browser is started, carry out the 
following steps:

1. On the Tools menu, click Internet Options.
2. Click the Advanced tab.
3. In the Multimedia area, click the Always Show 
   Internet Explorer Radio Bar check box.

Changing the Language of Menus and Dialog Boxes
-----------------------------------------------
Changing the language used in menus and dialog boxes may not 
work with all display adapters. If you see blank menus or 
dialog boxes after changing the language, try either of the 
following options:

- Change the resolution of your display adapter.
- Upgrade the driver for your display adapter to a newer 
  version. For information about updated drivers, contact 
  the manufacturer of your display adapter.

AutoComplete Options
--------------------
If you do not want AutoComplete to suggest matches for 
certain sensitive previously entered items, you have several 
options:

- You can delete a specific AutoComplete entry by highlighting 
  it in the AutoComplete drop-down list and then pressing DELETE.
- If you want to delete a user name/password combination on a 
  login page, delete the user name; the password will be deleted 
  with it.
- If you want to clear all form or password information, carry 
  out the following steps:

  1. On the Tools menu, click Internet Options, and then click 
     the Content tab. 
  2. Click AutoComplete, and then click Clear Forms or 
     Clear Passwords.

Microsoft Chat 2.5
------------------
You can no longer install Microsoft Chat 2.5 from the Internet 
Explorer 5.01 installation. If you previously installed Microsoft 
Chat 2.5 and then you upgrade to Internet Explorer 5.01, you will 
be able to continue to use your existing Microsoft Chat 2.5 
client for a limited time on the Microsoft Chat servers. If you 
do not have a Chat client already installed and you would like 
to install one, or if you already have a version of Microsoft 
Chat installed, consider installing the new MSN Chat from 
http://webchat.msn.com. 

Microsoft Wallet
----------------
Microsoft Wallet is no longer available for installation in 
Internet Explorer 5.01. If you have previously installed 
Microsoft Wallet and then you upgrade to Internet Explorer 5, 
you can continue to manage your wallet information from Web 
sites that invoke Wallet's interface, such as http://www.microsoft.com/wallet/downloads/manage.asp)

Enhanced Encryption Strength
----------------------------
Internet Explorer 5.01 now ships with standard encryption 
strength of 56-bit and supports the U.S. government standard 
for data encryption (DES). Moreover, the cryptographic modules 
in Internet Explorer 5.01 have been certified to be compliant 
with the Federal Information Standard (FIPS) 140-1. FIPS 140-1 
is a U.S. government standard that specifies best practices 
for implementing cryptographic software.


APPLICATION COMPATIBILITY
=========================

Visual Studio 6.0
-----------------
There are some known issues when you have Microsoft Visual 
Studio(R) 6.0 and Internet Explorer 5.01 installed on the 
same computer. These issues are resolved with Microsoft Visual 
Studio 6.0 SP3. If you are running Visual Studio 6.0, it is 
recommended that you upgrade to SP3 at 
http://msdn.microsoft.com/vstudio/sp/vs6sp3/.

DirecPC 2.0
-----------
After you install Internet Explorer 5.01 on a computer running 
DirecPC 2.0, you may receive an error message when starting 
the DirecPC software. To correct this problem, contact Hughes 
Network Systems to obtain an updated version of the DirecPC 
software.

BackOffice Small Business Server
--------------------------------
If you use BackOffice Small Business Server, you must upgrade 
to Small Business Server 4.5 before installing Internet 
Explorer 5.01. Without the upgrade, the SBS management console 
will flicker with each screen transition. Increasing the 
number of colors helps the problem but does not resolve it.

Logitech Internet Keyboard
--------------------------
Certain versions of the Key Commander software that ship 
with the Logitech Internet Keyboard are not compatible with 
Internet Explorer 5.01. For more information, contact Logitech 
Customer Support or see the Logitech Web site at
http://www.logitech.com.

Diamond Video Drivers
---------------------
If you are running Internet Explorer 5.01, then you install 
some Diamond video drivers (downloaded from the Diamond Web 
site or from CDs that come with Diamond video cards), you may 
not be able to restart your computer.

This is because the Diamond video driver installation replaces 
the Windows system file Comctl32.dll. Diamond is aware of this 
problem and is fixing their video driver installers. There are 
two options for addressing this issue:

Before you install these drivers:
  
1. Make a backup copy of the file Comctl32.dll found in the 
   Windows\System or \Winnt\System32 folder (the system folder).
2. Install the Diamond video drivers.
3. Restart your computer by using a bootable floppy disk.
4. After the restart is complete, copy the backup version of
   Comctl32.dll to the system folder, overwriting the existing 
   version of the file.
5. Remove the disk from the floppy disk drive, and then restart 
   your computer again. 

If you have already installed these drivers:

1. Restart your computer by using a bootable floppy disk.
2. At the MS-DOS prompt, change directories to the folder 
   containing the Internet Explorer 5.01 files. If these files 
   were downloaded, the default location is C:\Windows Update 
   Setup Files; or, on the CD-ROM, choose the IE5 folder under 
   the correct operating system.
3. Extract the Comctl32.dll file by using the following command 
   line: 

   For Window 95 or Windows 98:
   extract /e /l c:\temp setupw95.cab comctl32.dll
     
   For Windows NT:
   extract /e /l c:\temp setupnt.cab comctl32.dll

4. Copy the extracted Comctl32.dll file from the C:\Temp folder 
   into the Windows\System or \Winnt\System32 folder (the system 
   folder), overwriting the existing version of the file.
5. Remove the disk from the floppy disk drive, and then restart 
   your computer again. 

Internet Explorer ActiveX Tree and Pop-up Menu Controls
-------------------------------------------------------
During the installation of Internet Explorer 5.01, the Setup 
program removes earlier versions of the ActiveX tree control 
and pop-up menu controls due to compatibility issues with this 
version of the browser. Programs that rely on these controls may 
require reinstallation of the controls to restore functionality.

Task Scheduler on Windows NT 4.0
--------------------------------
Windows NT 4.0 included an old version of the Schedule service, 
also known as At service (Atsvc.exe). Internet Explorer 5.01 
upgrades it to the new version of the Schedule service, Task 
Scheduler (MSTask.exe) and converts At jobs to Scheduled Tasks.

With the old At service, all At jobs had to run in the same 
account as the service itself. The default account for the 
service was the Local System account, but it could be changed 
to another user account if desired. Some Windows NT 4.0 users 
changed the At service's account because they needed their 
jobs to run in a user account. 

With the Task Scheduler, each scheduled task can be configured 
to run in a different account. The Task Scheduler service itself 
has to run in the Local System account.

For backward compatibility, the Task Scheduler allows the user 
to set one account to use when running scheduled tasks that were 
created from At jobs. When Internet Explorer 5.01 is installed, 
this account is set to the Local System account. If you are 
running Windows NT 4.0 and you changed the account that the At 
service ran in to something other than the Local System account, 
then after installing Internet Explorer 5.0 you would need to 
manually re-enter the user name and password for that account. 
To do this, in the Scheduled Tasks folder, click the Advanced 
menu, and then click AT Service Account. 

This must be done manually because Internet Explorer 5 Setup 
cannot decrypt the password that was used by the At service.

For more information about At service compatibility, see online 
Help in Task Scheduler.
