Well, I had a look at the "Application Compatibility Toolkit"
recommended above, but could not work out how to handle it yet. Maybe
that is a solution, albeit a somewhat complicated one.

Running from an administrator prompt works, but might create files
with certain restricted rights. I will have to check if this works for
me. I could not find a "sudo" command to run the one problematic
program as administrator from the command prompt yet.

Thanks for your assistance.
