How can I clean my system .... ???

I downloaded winex and tried to install it. It couln't. I deleted the source directory, and when i try to install the other versions(i download them and install) they tell me that "old version is found" and don't install. How can I clean my system from older installations of winex if there is no more source directories(from where they were installed) ??? Can anyone advice the command like "rm *wine*" or something?
