VXDIAG PSA Diagbox License Invalid Solution

Vxdiagshop.com engineer did a Teamviewer check and found the solution.

Many software on his computer conflict with the diagbox software.

Since the VXDIAG PSA scanner uses a separate driver for diagbox, you should install Diagbox software on a separate laptop.

Then it should be fine.

How to Install Tech2win in PSA Service Box?

Here is the guide to install GM Opel Tech2win from PSA service box. PSA Group has added the Opel/Vauxhall Tech2win subscription as standard included in the GDS2 Subscription.

This works with Passthru tools such as vxdiag vcx nano gm, drewtech Mongoose GM, Drewtech cardaq, Cardaq m, Bosch KTS and even Ford VCM3. However it does not work with Autel Passthru :( you will need to make sure the relevant drivers are installed.)
Then go to Service Box. You MUST use Chrome as the browser and NOT Edge, Explorer or Firefox. For some reason the Java doesn't run properly on those.
