I have several apps installed on a Win2K machine, some made by our company, some not. None of our applications use the windows installer, theirs does.
When one of our applications is uninstalled, however, we start seeing a "Windows Installer: Preparing to install..." dialog box in various places. This happens when we try to run the other company's products, when we try to install the other company's products, and when we try to uninstall our other product.
This doesn't happen on all Win2K machines, only a handful. Any clues as to what could be happening?
