When Windows Will Not Let You Uninstall or Reinstall a Program
Office (and many other programs that use the Windows Installer Service) will often prevent reinstallation and uninstallation if there is a version conflict. This is how to correct this problem.
Programs that use Windows Installer Service are very picky about version conflicts.
Here is a common example. You install Office. It works well but something gets corrupted. You’ve lost your disc so you rebuild off the network or try to update online. Maybe you try to upgrade to the latest version. You get to a point that you can neither reinstall or uninstall and receive an error like one of the following:
This patch package could not be opened. Verify that the patch package exists and that you can access it or contact the application vendor to
verify that this is a valid Windows Installer Patch package.
This action is only valid for products that are currently installed.
Setup is unable to remove earlier version.
The feature you are trying to use is on a network resource that is unavailable.
Error 1612. The installation source for this product is not available. Verify that the source exists and that you can access it.
This is a very common and painful problem that is caused by the Windows Installer Service. The best solution is to use Windows Install Clean Up to blitz the previous installation. After you “clean up” the previous install, you will be able to reinstall the program that is giving you the problem.
The Windows Install Clean Up program is powerful and can be dangerous. Read the support article noted below before running it on your system.

Not in my case… I uses Windows Install Clean Up to try to uninstall Office 2003 in WIndows Vista. But it didn’t detect any apps at all.

This doesn’t work with Win7, would prefer a more up to date guide, please.
My issue is focused around IVT/bluesoleil not even existing in the “C:Program Files (x86)” after it’s ‘installed’.
So far, the only way to ‘fix’ this is to go into the registry and delete anything that is found via search containing IVT, or bluesoleil, which takes a long time to get done.

THANK YOU. I am a computer dinosaur. The OverDrive Media Console used to download audio books from the Boston Public library “suddenly” refused to download books. The Microsoft support was gobblety goop to me. Your info made some sense and I did what you said. Easy peasy. I am very grateful. Thank you.

I am directed to another article which informs me that…
“The Windows Installer Cleanup utility (MSICUU2.exe) that was previously referred to in this article resolved some installation problems but sometimes caused issues with other programs or components that are installed on the computer. Because of this, the tool has been removed from the Microsoft Download Center. ”
Darn.
