Try uninstalling Melodyne.
When the red box comes up, note the file name in the red box. It will be C:\Windows\installer\ee01151.msi or something similar.
Press the Windows key.
Type "Command" do not press enter or click anything
Select "Run As Administrator" (see attached photo)
Type: cd C:\Windows\Installer
Press enter
Type in the filename: ee01151.msi or whatever yours read from step 3.
Press enter
You should now be able to uninstall.
