3). Question:

Recently, in the course of using VXDIAG VCX NANO for GM on Win10 Home system, the error message “No Valid Lease Found” prompted.  Look at the following pictures.

Then I consulted VXDIAG engineer who said that the problem was caused by the system of Windows I used and suggested that I should stop using Windows 10 Home. After that, I changed the system of Windows and used Window 7 Professional instead.

However, the problem still existed. Again, I consulted VXDIAG engineer and he said that the storage capacity of my computer memory was too small. Besides, he also advised that I should use the newest version of GDS2 patch to crack. I followed his advice and solved my problem.


So DON’T install GDS2 on Windows Home operation system (Win7 Home, Win10 Home etc) and make sure your computer system has enough storage space.
