I want to uninstall MAMECE3 so that I can move it out of main memory onto a CF card, but when I go to remove it (either from Remove Programs or through ActiveSync), it complains that \Program Files\MameCE\MameCE3.exe is either in use or is read-only.

It's not in use, and I can't seem to figure out how to clear the read-only flag.

Any ideas?
