I just successfully installed MTH 4.3 updated files to my TIU, but I can’t upgrade the remote with the same 64 Bit, 2.3 driver software. When I run the software and try to upload the remote file, that I unzipped, it is asking for a file with a txt extension and the one that comes with 4.3 has a rem extension. Manually changing the extension is not helping. Where did I go wrong.
Help, Blake
