Tryign to uninstall drivers

I'm trying to uninstall the AMD Catalyst Install Manager, but get this error when I do:

---------------------------
"C:\Program Files\ATI\CIM\Bin\InstallManagerApp.exe"
---------------------------
Windows cannot find '"C:\Program Files\ATI\CIM\Bin\InstallManagerApp.exe"'. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.
---------------------------
OK
---------------------------

I checked the folder and it's not there. What does this mean? How do I uninstall it? Thanks
