Turns out my Windows 10 was actually fine. I tried again last night, and actually found some registry remnants for Grand Prix 4 which made it look like it was still installed, and the folder was still there with some of the files, so it looks like it got corrupted when I uninstalled it for a clean install, because when trying to run the full game installer, it still gave me the same error.
I used RevoUninstaller and removed all of the registry entries, and also deleted all files related to InstallShield in c:\Program Files(x86) and c:\Program Files(x86)\Common Files. After that, the installation ran fine.
Hope this helps somebody.
