File.Move("c:\\3c\\install\\builds\\output\\setup", "c:\\3c\\install\\builds\\Renamesetup\\newsetup");

This assumes that the file "setup" does not have an ".exe" extension. Also, the new file will not have an ".exe" extension.

The folder "Renamesetup" must exist in advance, otherwise you must create it in your code using Directory.CreateDirectory.

Please note that you have to "quote" the backslashes using "\\" as I've done above. This only works if "setup" is a file!

The path makes it look like setup is a directory. If so you should use

System.IO.Directory.Move
