VXDIAG VCX NANO GM GDS2 “No TIS Connection Available” Solution

VXDIAG VCX NANO GM GDS2 “No TIS Connection Available” Solution

Here comes the vxdiag vcx nano GM GDS newbie software installation experience on Windows 7 64bit system, including errors and solutions.
8:22AM 01/10/2021:
I bought the vcx nano for gm when i get to the  GDS2 screen I receive the ‘No Valid Lease Found’ message. I’ve reinstalled the software, tried running from the patch, tried on different computers, to no avail.
Computers are running Windows 7 Professional with at least 4 GB of memory.
9:01AM 01/10/2021:
I found that I needed to put the GDS2 patch exe in the GDS 2 folder in:

c:\Program Files (x86)\GDS 2\

When I ran the patch from there after a couple of tries it did come up with ‘8851 Days Remaining Until Lease Expires’.

So, progress.

But now I get this message in GDS 2:

‘No TIS Connection Available’
9:33AM 01/10/2021:
I finally got it.  I had to work through a number of errors.  I’ll detail the process here in case it might be of help to someone else.

No valid lease – once that was solved,
No TIS connection available – fixed that then,
No diagnostic packages loaded – got that,
Finally, no connection to car using the Bosch driver

Basically, I had to reinstall everything to get it to work on Windows 7 Professional 64 bit:
VX Manager v1.8.4 Build 0315.  This gave me the VCX.bin v1.8.4 and the SDK v1.8.4
GDS 2 v22.1.00900 with GM Global v2020.7.1 and GDS 2 Java v14.00000
GM MDI Manager v8.5.33.78 – don’t know if that was strictly necessary, but it didn’t seem to hurt.

Steps I needed to take to run successfully:
I started the VCX Manager, let it detect the scanner, updated licenses, did not update GDS2 in Manager, and left the program running.
Started GDS 2 from the standalone icon (not from the VCX Manager).  It comes up with an error #6 and then ‘No valid lease’.
Closed GDS 2, then immediately restarted it again.  This time it opens with no error and 8000+ days until the lease expires.

Then I was able to successfully choose the scanner and connect to the car.
Hope it helps.
