When you install SAS 9.1 on Win2000 with SP3 and SP4, this message
might appear repeatedly:

   Reboot Pending.

This message appears when an installation of a third-party application
attempts to install files that are in use by the Windows operating
system. This installation leaves the Windows registry in an incomplete
state. This is controlled by the Windows operating system.

In most cases, rebooting your PC clears the the error message. However,
if multiple reboots are required, SAS continues to give this message
until all of the necessary reboots are performed.

The following are items that might cause this behavior:

   * Installing a Windows service pack and not rebooting your system.
   * Installing critical updates and not rebooting your system.
   * Installing products and a reboot needs to be performed.
   * Icons in the right-hand corner waiting for you to perform system
     updates.
   * Adware or spyware (see SAS Note  #12469 ).
   * Temp files that need to be deleted

When you install products, not just SAS, reboot your system after each
installation is completed. This prevents the operating system from
placing pending keys in the registry. If there are several reboots
required, you need to reboot as many times as necessary.

In an extreme case the following steps were taken. Please remember that
this is not the recommended way, and always back up your registry before
making any changes:

   1. Reboot your system.
   2. Log in as the Administrator.
   3. Close all applications including anti-virus software (even if
      it is just running in the background).
   4. Go to the system registry by clicking on Start>Run and typing
      regedit.
   5. Examine the following Windows registry key:

      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
      Manager

If it contains FileRenameOperations or PendingFileRenameOperations,
delete this key, and retry your SAS 9.1 installation.

Warning: Always back up your registry before you make any registry
changes. For assistance, see Windows Help, Microsoft documentation,
or the Microsoft Windows Web site. SAS is not responsible when
you edit the Windows registry: changes in the Windows registry
can render your system unusable and will require that you reinstall
the operating system.

Please note however, your operating system might still require a reboot
in order for you to continue with the install.

If you still have problems with this make sure that you have clean
PC (no spyware or adware).
