This can occur if the software protection stuff is turned on for Windows 10 or 11.

Turn everything OFF for "Virus & Threat Protection" and "App & Browser Control."

Those two security features limit access to certain areas of the registry. Depending on the installer that's used, it might not be able to work around it.

This is an issue with a lot of enterprise software, as it's usually older in make.

I ran into this issue with Schneider Electric (Andover) Continuum Cyberstation. There were issues with badge printing. After working on the issue for HOURS including installing Windows 10 clean on a new VM, at home, with no antivirus software, and running into the same issue, I started digging into the registry. I found that there were entire registry folders that were missing.

After poking around, I found that the issue was a combination of Windows security features. Turning off all of the active stuff, before installation was the fix.

Oh, and it worked for the SINEMA RC Client as well.

Thank you very much, it worked for me on Windows 11, although first it asked me to update .net 3.5, then the message appeared again, I had to delete it from the registry and that's it, it allowed me to install again, thank you.

Funcionou!

It Works!

So let me understand as it is happening to me after FIVE years since your post: Siemens cared so much about this issue that they never changed this useless message, leaving the installer searching for info in forums and blogs. 

Whatever the reason (it can be any of the tons of Windows issues, old .NET versions, or planets alignment) we need to know how to solve it. If it is not an issue of your software, it must be indicated clearly during installation after setup checks if all known weak points have been verified (users and group settings, available space, whatever the hell). 

If this error is generated by a wrong entry in Register, it MUST be fixed automatically by setup. 

Siemens! Wake up! We are not your beta-testers.
Your software is damned expensive, not a free Linux opensource you need to tweak to make it work.
