If for any reason you need to uninstall EasyWorship, or if you need to uninstall and reinstall, you can do so by going to Apps and Features in the Windows Control Panel, select EasyWorship and click Uninstall.

Uninstalling EasyWorship will only remove the program itself.  It will not remove any of your data (songs, media, presentations, schedules).  

If you would like to remove or backup that database, the default location for that information is:

C:\Users\Public\Public Documents\Softouch\Easyworship
