Problem:
Failed to install driver for VXDIAG VCX NANO GM scanner. VX Manager gives error MDI driver not installed and device license for this application is invalid or expired.
Solution:
Usually, you don’t need to install SGM RDS driver. It is for Chinese brands.
If need to diagnose Chinese GM with RDS, your license has expired. Update license before installing the SGM RDS driver.
Update:
Got the license update. When installing driver again, it says GM GDS2 or Tech2win Software Not Installed.
Solution:
Just as indicated, install GDS2 and Tech2win software, then install this driver.
