It runs. Administrator or not, remove folder or not... No problems.

But the problem is .. program keeps reverting back to version 3.254 automatically by itself.

Any ideas why this happen ?

The icon on desktop says it's 3.26.0, but in the About window, it says 3.254.
I tried to reinstall with Repair and Modify option, but still same situation.
I tried to uninstall and install again, still the same happens.
