Cannot install Campaign Vietnam

Used to have this on D drive. Drive had to be entirely replaced after catastrophic failure of the SSD. Re-bought Campaign Series Vietnam (thinking it was a new release). Went to install on the new blank D Drive. Refuses to install telling me I have a previous version which needs to be uninstalled. I don't. Tried 3 uninstallers to look for vietnam in the registry - nothing. Tried it myself manually - nothing there. Now I'm totally stuck and cannot install version 2.00 which is the only download I have.

I need a workable solution possibly a link to an earlier version which I can install and then uininstall. But I'm guessing. You're the experts. What's the solution??

Hello, sorry to hear you're having these issues. We would recommend reaching out to our Tech Support team at support@matrixgames.com and explaining the issue to them. It sounds like whenever CSVN was removed or uninstalled previously, it wasn't cleared completely from the registry. Our Tech Support team should be able to guide you through the process.
