so having major issues with this on windows 7 and wasn't sure where to post since i just got this today and can't even read my own car... followed all of the install walkthroughs on here and had .net framwork 2.0 installed previously since i used a DHP tuner previously that needed 2.0... tuner is trying to read a 2001 Impala LS with a 3.8 L and it's not seeing the VCM at all. Tried reading my buddies 2004 Grand Prix GTP Comp G 3.8 S/C and it couldn't read the VCM either... not sure what to diagnose since i've got the 64 bit drivers for the MVPI, made sure .net 2.0 was installed about 4 times now and restarted after every uninstall and reinstall, along with making sure that every cable was connected properly and securely... i have a log file that i uploaded from vcm suite if it helps... thanks in advance
