To enable the UAC, type ‘uac’ in the Start Search. You will see Change User Account Settings. Click on it to open the User Account Settings applet.
Move the slider to the lower-most position to disable the User Account Account.
Click OK and exit.
Now try and see if you can open the app.

Navigate to the following key:
