SYSTEM REQUIREMENTS
===================

To run Internet Explorer 4.0, your system must meet the following 
minimum requirements:

- A 486 with a 66 Mhz processor (Pentium processor recommended)
- For Microsoft Windows 95:
  8 MB of RAM minimum, 16 MB with Active Desktop
  For Microsoft Windows NT:
  16 MB of RAM minimum, 24 MB with Active Desktop
- For Microsoft Windows NT: 
  You must be running Service Pack 3 (or higher)
- 40 to 70 MB of hard-disk space (depending on installation type) 
- Mouse
- Modem
- CD-ROM


SETUP
=====

- Before you install Internet Explorer 4.0, you should make sure that no
  scheduled tasks are running, because they might interfere with the Setup 
  process.

- CAUTION: Do not install any previous version of Internet Explorer over 
  Internet Explorer 4.0. If you need to install an earlier version of Internet 
  Explorer, you must uninstall Internet Explorer 4.0 first.

- If you have been using Platform Preview 2 release of Internet Explorer 
  4.0, you should uninstall that version before installing the final version. 
  During the uninstall process, you will be prompted to save your Outlook 
  Express preferences; they will be used to set up Outlook Express when you 
  install Internet Explorer 4.0. 

- It is recommended that you download Internet Explorer 4.0 to a 
  directory that does not contain any other files and that will not 
  be used for any other purpose. If for some reason you want to 
  uninstall the Setup files, the download directory will be removed. 
  For information about removing the Setup files, see "Installing Internet 
  Explorer 4.0."

Installing Internet Explorer 4.0
--------------------------------
Whether you choose to install over the network or to download the 
installation files to your hard disk, the Setup files are copied to 
your hard disk. This is so you can reinstall more quickly if you need 
to. 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 4.0 Setup Files.

You cannot install Internet Explorer 4.0 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 4.0 to a 
UNC path.

If Internet Explorer 4.0 appears to stop responding at the end 
of Setup, you need to restart your computer manually. 

Running Internet Explorer 4.0 on Windows NT
-------------------------------------------
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 
4.0. This is also true for some add-on components.

If you're running Internet Explorer 4.0 on Windows NT, you must 
set user permissions to Full Control for the Temporary Internet 
Files folder (cache). The user must have write permission in order 
for files to 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 4.0, 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.dl
3. Click OK.

Running Internet Explorer 4.0 on a Dual-Boot Operating System
-------------------------------------------------------------
If your computer is set up to dual boot between two operating 
systems, you must install multiple instances of Internet Explorer 
4.0 in a separate directory for each operating system. For example, 
if you are running Windows 95 and Windows NT, you might want to 
install Internet Explorer 4.0 in C:\IE95 for Windows 95 and in C:\IENT 
for Windows NT. Do not try to use the same installation of Internet 
Explorer with two operating systems. If you later uninstall Internet 
Explorer 4.0, one of your operating systems may be left unbootable if 
you don't follow these steps.

Note also that if you dual boot between two operating systems 
that are configured to share a Program Files folder, and you 
uninstall an add-on component from one of your Internet Explorer 
4.0 installations, it will be removed from both of them. This is 
because the add-on files are stored in the Program Files folder.

Uninstalling Internet Explorer 4.0
----------------------------------
You can uninstall Internet Explorer 4.0 by carrying out the 
following steps:

1. In Control Panel, double-click the Add/Remove Programs icon.
2. Click Microsoft Internet Explorer 4.0, and then click Add/Remove.
3. Follow the instructions on your screen.

Cannot Use Registry or ERD Files Created Before 
  Installing Internet Explorer 4.0
-----------------------------------------------
If you install Internet Explorer 4.0 and then restore a Windows 95 
registry that was created before you installed Internet Explorer 4.0, 
or use a Windows NT Emergency Repair Disk (ERD) that was created 
before you installed Internet Explorer 4.0, you may be unable to 
start Windows 95 or Windows NT 4.0.

To resolve this problem, use the Ieremove.exe tool to remove Internet 
Explorer 4.0. For information about how to do so, open the Microsoft 
Knowledge Base at http://www.microsoft.com/kb/default.asp, and then 
see the following articles:

  For Windows 95, see Article Q166313, 
  "Removing Internet Explorer 4.0 for Windows 95 Using Ieremove.exe"

  For Windows NT, see Article Q166314,
  "Removing Internet Explorer for Windows NT 4.0 Using Ieremove.exe"

Adding or Removing the Windows Desktop Update
---------------------------------------------
To add or remove the Windows Desktop Update, carry out the following 
steps:

1. In Control Panel, double-click the Add/Remove Programs icon.
2. Click Microsoft Internet Explorer 4.0, and then click Add/Remove.
3. To remove it, click "Remove the Windows Desktop Update component 
   but keep the Internet Explorer 4.0 Web browser."

   To add it, click "Add the Windows Desktop Update component from 
   Web site," and then follow the instructions on the screen.

NOTE: For this release, clicking "Add the Windows Desktop Update 
component from Web Site" opens the Internet Explorer 4.0 components 
download page so you can download and install the Windows Desktop 
Update. If you have previously downloaded or installed the Windows 
Desktop Update, you can enable it without connecting to the Internet 
by running IE4setup.exe from your local Internet Explorer 4.0 Setup 
folder. When prompted, click Yes to enable the Windows Desktop 
Update, and then choose to upgrade only newer items.

Installing Internet Explorer in a Language Different 
  from the Operating System Language
----------------------------------------------------
If you install a version of Internet Explorer in a language 
different from the language of the operating system you are 
running, the Windows Desktop Update will not be installed.


CONFIGURING SUBSCRIPTIONS IN AMERICA ONLINE
===========================================

If you want, you can manually update your subscriptions through 
America Online by carrying out the following steps:

1. Right-click the Internet Explorer icon, and then click Properties.
2. Click the Connection tab.
3. Select the "Connect to the Internet using a local area network" 
   check box.

NOTE TO FRENCH USERS OF INTERNET EXPLORER 4.0
=============================================

In order to comply with French laws on the use of encryption 
material, the following features have been disabled for users 
in France:

- S/MIME support in Outlook Express
- The Microsoft Wallet secure storage feature
- PCT 1.0 support

However, SSL 2.0 and SSL 3.0 support are authorized, and are

KNOWN ISSUES
============

PICS Support in Internet Explorer 4.0
-------------------------------------
The Internet Explorer Content Advisor uses PICS (Platform for 
Internet Content Selection) ratings. Please be aware of the 
following items:

- The PICS rating is not used for documents using the file:// 
  protocol.

- If you have ratings enabled, they will apply to items that 
  you have added to your Active Desktop. A "Navigation Canceled" 
  message will be displayed instead of Web content for Active 
  Desktop items that are blocked due to content ratings. 

Some Programs Do Not Detect Browser Version Correctly
-----------------------------------------------------
Some third-party Internet-based programs use nonstandard 
methods of detecting the current browser version. If you 
experience this in a program you are running, please contact 
the program vendor for an update.

Temporary Internet Files are Replicated 
  to the Home Directory of Roaming Users
----------------------------------------
The Temporary Internet Files folder is replicated to the home 
directory of users with roaming profiles. If you are running 
Internet Explorer 4.0 on a Windows NT system, this may cause 
disk-space problems on servers with numerous roaming users or 
with several users who have with large caches. To set cache size, 
click the View menu, click Internet Options, and then click the 
Settings button.

Using NetMeeting When Internet Explorer 4.0 Is in Offline Mode
--------------------------------------------------------------
If you start NetMeeting with Internet Explorer 4.0 in Offline 
mode, NetMeeting will not start properly, although no error 
message appears. To work around this problem, dial up using RAS 
for Windows NT computers or Dial-Up Networking for Windows 95 
computers. Or, in Internet Explorer, click the File menu, and 
then click Work Offline to clear the check mark.

Access Aptiva Issues with Internet Explorer 4.0
-----------------------------------------------
The Access Aptiva component of the IBM Aptiva PC does not render 
properly with Internet Explorer 4.0. To get an updated version of 
the Access Aptiva program, you can either go to the IBM home page 
at http://www.us.pc.ibm.com/aptiva, or click IBM Update Connector 
on the Start menu, which automatically downloads the updated 
components.


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

Adobe Acrobat: Using Internet Explorer 4.0 with 
Adobe Acrobat Reader 3.0
-----------------------------------------------
Using the Adobe Acrobat .pdf viewer in Internet Explorer 4.0 
may not work. You can download the latest version from 
http://www.adobe.com.

Also, if Content Advisor is turned on in Internet Explorer 4.0, 
you cannot view .pdf files in the browser.

CleanSweep: Critical System Files Replaced
------------------------------------------
If you are already running Internet Explorer 4.0, installing 
CleanSweep 3.0 is not recommended. CleanSweep replaces vital 
system files and will cause both Internet Explorer and the 
Active Desktop not to work properly.

If you must install CleanSweep, please visit this site for 
instructions:

http://www.microsoft.com/iesupport/ie40/content/ie4txt/appcompat.htm#cleansweep

DEC ClientWorks: Remove Xdmisrv.exe Before Installing 
  Internet Explorer 4.0
-----------------------------------------------------
If you are running DEC Client Works on a computer with Windows 95 
and with no networking services installed, you should remove the 
file Xdmisrv.exe from your startup group before installing Internet 
Explorer 4.0. Otherwise, you may see the following error message when 
your computer restarts after installation: "RPCSS caused an invalid 
page fault in module OLE32 at 015F:7FFBAD35." This error does not 
occur if any networking services are installed, including Dial-Up 
Networking. This issue has been fixed in DCOM95 1.1, which you can 
download from http://www.microsoft.com/com/.

Microsoft Money: Requires Updated 128-bit Extensions
----------------------------------------------------
If you install Microsoft Money 97 on a computer running Internet 
Explorer 4.0, please go to the following Web site: 

     http://www.microsoft.com/ie/ie40/download/128bit.htm

in order to get the updated 128-bit extensions required for online 
banking with Microsoft Money (U.S. and Canadian users only). Until 
these extensions are installed, you will not be able to do online 
banking.

Norton Utilities and Norton Navigator
-------------------------------------
- Norton Utilities version 2.0 is not compatible with the Internet 
  Explorer 4.0 Recycle Bin because of new features that have been 
  added to Internet Explorer.

- If you are running Norton Navigator, note that the Control Panel 
  shortcuts on the Start menu do not work.

- If you reposition the taskbar to the left or right side of your 
  desktop, the Norton Navigator quick launch area disappears.

- If you are running Norton Navigator, you need to disable the 
  Norton Taskbar feature in order to use the functionality of 
  the new Internet Explorer 4.0 taskbar.

--------------------------------------------------------
In the Procomm Plus 95 Web browser, the Browser Properties control on 
the Setup menu does not work. However, you can set browser properties 
by double-clicking the Internet icon in the Windows Control Panel. 
Property settings for the Internet Explorer 4.0 browser will also 
apply to the Procomm browser.

Stacker: Size of Host Drive Must Be Increased
---------------------------------------------
If you run Stacker 4.1 on a computer with Internet Explorer 4.0, 
you must increase the size of the host drive. If you do not increase
