I know some people here have experience with Windows installers, so I thought I'd ask.

I have an application that I need to install on my Windows computer that refuses to install. It does install on another Windows computer. It is a distributed as an MSI.

It goes through the whole install process and claims that it installs properly, and then tries to start the application and fails saying it can't find the executable. The location where it gets installed on the computer where it works doesn't get created. Tracing the process with Process Monitor doesn't seem to show anything trying to access that directory at all.

What sort of further troubleshooting steps can I take?
