This is a generic error caused by various facts like registry error, registry access, file corruption, compatibility, etc. The first thing I would recommend is its re-install. Firstly, remove the application using Uninstall a program in Control Panel, then run CCleaner to remove the obsolete registry items.
Secondly, download and install the software again, but this time run the installer as Administrator. You can do the same thing when you want to start the software. Right click the icon and select Run as Administrator.
