The file is already called LANClip.exe. Nobody else has any trouble running it.
Bear in mind that under XP, LANClip will probably just crash. This version isn't very good. I've handed development of the PC version over to someone else who will do a better job, but he's since done absolutely nothing... *sigh*.
It makes no odds to me, since I gave the PC that I borrowed to write it back to its owner.
