VXDIAG GM MDI “Manager Initialization Error”

Here is the solution to VXDIAG VCX NANO for GM/Opel GM MDI Manager Initialization Error.

I have a new VXDIAG VCX NANO for GM.
It worked yesterday with Saab 9-5 2006 (9.250 bin, with problems but it can read trouble codes and make some config).
Today I want to make a clean installation on VMware with Windows XP image.
After installation I can not run GM MDI Manager.
1. If I choose UNINSTALL in “MDI Select” I can open MDI Manager and manager can not find any interface. (drivers installed properly)
I have only “Not connected to MDI”.
2. If I choose INSTALL – I have an error.
“Manager Initialization Error [Failed to initialize Vetronix Runtime rc = -5]”
Also I don`t have any table with interface option to choose at the start of Tech2Win.
(because MDI Manager didn`t find pluged any interface?)
I can find VCX Nano and configure with VX Manager.


If your running in VM make sure your OS didn’t connect to it via wifi etc. You want your VM to set up the drivers not the primary OS. If it did just disconnect in primary OS on network and try again in VM.

Please refer to the following:
Tech2Win Install(WIN XP or WIN 7)
1. Run Tech2Win\AutoInstall.exe, Everything will be done.
2. install VX Manager.
3. Open VX Manager, install GM Driver.

Running GDS2 with VMWare
1. Install VMware-player-6.0.6-2700073.exe
2. copy GDS2 VM to harddisk.
3. open GDS2 VM with VMware Player
