For various reasons, I need to install a third-party program on a Windows 7 VM running under Parallels Desktop 18 on a MacBook Pro running OS 12.6.1.

The problem appears when I try to run the downloaded setup.exe file (as admin or regularly): an error message is shown saying that "Setup has detected that the publisher of file [xxx] cannot be verified" (see image), and the execution cannot continue. Note that on a native Windows computer under Windows 7, this operation proceeds without problems and the program is installed.

I have searched for a fix for this, but almost all posts found are concerned with a warning message (that can be overridden) about an unidentified publisher. This is something else – no override option. I have also tried to

  • unblock the program in Properties (but it is not marked as blocked)
  • remove the publisher from a list of untrusted publishers (could not find the publisher, and no publisher could be removed anyway)
  • edit in regedit to list *.exe files as low risk (nothing happened)
  • running the setup.exe from the cmd.exe tool as admin (same error message)

Any helpful hits are appreciated.

If you download that file from another source like https://dotnet.microsoft.com/en-us/download/dotnet-framework/thank-you/ … can be possible to overwrite that file and try to see if now it continues? or some .exe with that name, and try to continue setup... you can later (or previously) install net framework 4.6.2 to make it to work...
