That is one issue I have never seen posted to the forum before! It seems you installed the program as a "standard" user and not as your computer's admin. Is that correct? If so, unless any other user has better ideas I can think of only two possible solutions for you:
On the desktop icon, when you want to launch the program right-click and choose the option to "Run as admin".
If that fails, you may have no other choice than to fully uninstall the app and then reinstall, ensuring you are logged in to your computer as the admin.
