Performance Optimizer does not work or has never work. I recently upgraded to the Pro version in hopes that I could have a software with all the bells and whisles. Well, some of the bells are not workking - Something went wrong pops up when I try to use Performance Optimizer.
CCleaner Professiona v6.19.10858 (64-bit)
Windows 11
Windows Defener (deactivated)
Windows Defender Firewall (allowed)
CCleaner64.exe run as an administrator
None of the the above changes anything. There is quite some traffic in the Forum about this issue and I could not see / find a solution.
