When I am trying to install a program (PlayOnline), I run the setup and then it tells me it is already installed (it's not, but I might have some random registry entries left around from it).

So when it takes me to uninstall it, it instantly fails saying:

"Error -1605 This action is only valid for products that are currently installed.

This means it's a Windows Installer Service. Looking at this: http://consumerdocs.installshield.co...8474&sliceId=1

It doesn't show up in Windows Install Clean Up.

The REINSTALLMODE thing is what I want, since I need to force it to install. But unless I'm getting the syntax wrong, it's not working. I run setup with that syntax and it still checks for an install and proceeds to make me try to uninstall it.

This is in Windows 7 (64bit) and this is a 32 bit program.
