acdsee issues

I have it as my default picture viewer but no longer runs when I try to open a picture. It just gets stuck as a background process but it never starts. The only way for it to run is to open the program either via the direct access at the desktop or through the program list at the start menu.

The Database option at the program is also broken with the option to rebuild thumbnails greyed out and the Maintenance one opening the pop-up window just to get stuck on screen and needing to force the program to close via the Task Manager. Furthermore, the Image database file (ImageDB.dtf.DFF) is nowhere to be seen at the direction indicated by the program itself.

Attempted fixes:

-Running the program in Compatibility mode
-Running it as Admnistrator
-Removing and reinstalling the program as Administrator. Oddly enough, after uninstalling the program and running Ccleaner to clean the registry, after reinstalling the program it will default to the last visited location; instead of the default location ACDSee opens after a clean install.

Recent changes: Only the default Windows Updates.
