Windows 10: Windows 11: Can't install ACT6 a legacy program

Forgive me if I am in the wrong forum... My question relates to Windows 11. I recently migrated from Windows 7 to Windows 11 and found that one of my legacy programs ACT6 won't install.

Windows Installer Issues! Can´t Install Programs on Windows 11.

Did you see my warning under the WIndows Club link in my last post to avoid Restoro which is a PUP? If you'd miss that I wonder what else was missed. Absolute thoroughness is required in these issues, skipping nothing and asking back if you need any help to complete a step. We often find out later that the fix was the skipped step, so please do not skip any. If you need help performing any step I will help.

I would uninstall Restoro ASAP and run System File Checker/DISM in WIndows 11:

If that doesn't fix it then you can do a Windows 11 Repair Upgrade which reinstalls Windows while saving your files and apps in place, brings it up to the latest version by the most stable method, takes about an hour and resolves most problems: https://www.elevenforum.com/t/repair-install-wi...
