Windows Installer Appears Every Time a Program Is Started.
This is a known problem with the Microsoft Office installation program, and with some
other packages that use the Microsoft Installer service.
If someone has ever started to install one of these programs on your computer you
may see this problem, especially if the installation wasn't completed
(was cancelled, or didn't finish for any other reason).
Usually, the problem can be fixed by completing the installation that restarts
inappropriately. You can then uninstall that package if you desire.
Microsoft has also posted several fixes on its support web site at
Microsoft has also written a utility that may help with this problem.
It can clean up information left behind by failed installations.

My programs are just innocent victims of this bug, present in the installer
used by some other programs.
