Hi,
If you need to act as an Administrator, you should know the Administrator's password !
When you call the Uninstall program by clicking on it, it's either by left-clicking twice (standard user) or by right-cliking once : in this case, within the window next prompted, you get the option to run the program as an Administrator : to proceed forward, you are expecter to enter the Administrator's password !
If you don't know that password, there is no way to proceed further with the Administrator's rights... :(
