How to Solve VXDIAG Tech2Win Device Not Connected?

Problem:

I got the vxdiag vcx nano gm tech2win software installed on a Win10 64bit laptop, software is installed but when run tech2win software, it will not communicate with the vehicle (2011 Chevrolet Colorado 3.7 4wd). Error device not connected. Any solution?

Solution:

VXDIAG Tech2win can be installed on 32-bit system ONLY. Better Windows 7 32bit system.

Some managed to install it on Win10 32bit, but some failed. Win7 is recommended.
