I've installed Delphi 7 on my Windows 7 at the time, ran really good and kept developing code as normal.

Then eventually that same laptop got upgraded to Windows 10 and this same Delphi kept working as expected (compile, edit, ..).

Maybe your colleagues can try to install it with the UAC disabled?

I think it has something to do with the 3rd party libs we're using.
