On a Windows 7 64-bit desktop, there is a program on the Programs and Features list (Control Panel\All Control Panel Items\Programs and Features) that refused to uninstall. The error obtained is:
Error 1723. There is a problem with this Installer package. A DLL required for this install to complete could not be run
I suspect filer were deleted or corrupted. The big problem is that the program refused to install itself over the broken version.
So how to I manually clean up the list of installed program?
