The Windows Installer is a global application used to install many Microsoft
products, including Office 2000 and Office XP, and is even available to
third-party developers to include with their programs.
Unfortunately, it's fraught with bugs, one of which is its tendency to
appear every time you start Office (or some other programs) and begin a
reinstallation or reconfiguration process. All you'll see is the "Please
Wait" screen, followed by a progress bar. The problem is related to the This
feature will be installed when required option (sometimes called "Install on
Demand"), used when installing some applications. In essense, Windows
Installer starts to install a "feature" when it is needed, even though it
may be already installed.
Unfortunately, but not surprisingly, Microsoft will not acknowledge that
there is a serious flaw in thier installer software. Here are the solutions
we've come up with so far:
? Reinstall the application in question, and don't choose the This feature
will be installed when required for any of the optional components.
However, this may not solve the problem (which is the very bug we're talking
about). We're currently looking for a way to fix the problem properly, but
in the mean time, here's how to turn off the "feature:"
? Open the Group Policy Editor by selecting Run from the Start Menu, and
typing gpedit.msc. (If the file is missing, run mmc.exe instead. Then,
select Add/Remove Snap-in from the Console menu, click Add, and double-click
Group Policy. Click Finish, then Close, then Ok.)
? Expand the following branches:
Local Computer Policy \ Computer Configuration \ Administrative Templates \
Windows Components \ Windows Installer
? Double-click Disable Windows Installer to your right, click Enabled, and
choose Always from the list. Click Ok when you're done.
? The change will take effect immediately. If you added a snap in, as
described above, you don't need to "save changes to the console."
? Note: If you encounter an error about the Administrator Policy the next
time you try to install an application, you'll have to re-enable the Windows
Solution #3 (for Office 2000 only):
? Run the Registry Editor (REGEDIT.EXE).
? Expand the branches to HKEY_CURRENT_USER\ Software\ Microsoft\ Office\
? Delete the UserData value on your right, and close the Registry Editor.
? The next time you start an Office application, it will ask for your
username, but shouldn't bother you again.
Hope this helps. Let us know.
