TCU TurboLamik

after a lot of messing about i had to set the program combability to windows 7 for it to work and detect the TCU
after that go to the tools tab then preferences ,there's 2 tick boxes make sure the top one is no ticked
this is my experience to get everything too work hope it helps someone else

I'm using a surface laptop with windows 11 and it worked right away. Maybe the version of windows 11 you have with the issue is outdated and it was patched at some point...

Glad you figured a way around it anyway.
