Tech2win allows General Motors Tech2 diagnostic software to run on PC.
One review I read talked about a couple days getting it to work and it won’t do all programming an actual Tech 2 can do. I would image most geeks can get it to work on their laptops, but that stuff is over my head. Seems it is kind of hit and miss what it’ll run well on. Tech2win is Tech 2 emulator software and needs a 32 bit OS or can be run in compatibility mode.
