Program should work fine on non English versions of Windows.
The permissions tool my program uses doesnt support *
So c:\windows\*.* would give that error, same as setting permissions in the registry. So this is a normal error I see with it.
On your Windows drive you should see "Tweaking.com_Windows_Repair_Logs" which will have more detailed logs. We can see if those show anything.
get rid of the nested "Application Data" folder
Can you explain on that a little more and what your trying to do?
