Qt 5.1 Package manager refuses to work

I am trying to uninstall just Qt Creator after I installed the stand alone 2.0 version. I launch “Uninstall Qt 5.1.0” from the Start menu and select “Package manager” then click Next. An error message shows up saying “At least one valid and enabled repository required for this action to succeed.” Is “Remove all components” the only option for the uninstaller? PS. This is on Windows 7.
