When opening DSS player after modifying the registry or profile settings you might get the following error message

The application cannot be executed because the following Shell Folder defined in the registry cannot be found. Please contact the system administrator. Templates

Open up Regedit and browse to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders

Check for Templates

In my case the following folder was not available

%appdata%\microsoft\windows\template

Recreating this folder fixed the problem. This error message might also display MyDocuments , So I would check the My Documents path in Olympus in the program if you can get in or the registry is set correctly. If not reinstalling should recreate this!
