Possible to install Tech2win on Windows 10 32/64 bit?

Is it possible to install GM Tech2win on Windows 10 32 or 64 bit?

That’s what lots of people are looking for. Have read a lot threads and posts on the web and made a collection here. Maybe it helps.

Here you go.

Lenovo Windows 10 32 bit: works good

An excellently designed device. Allscanner LTD made a better product than any of GM’s partnership with German owned Bosch diagnostic tools and for a lot less money. I was able to reprogram a 2008 Cadillac XLR ECU in under 4 minutes using just a Lenovo Windows 10 Celeron laptop. It would have taken around 15 minutes with my Tech2 with CANdi module with serial to USB interface (what an outdated mess). The VX manager runs fine on Windows 10 and so does the Tech2Win program (I don’t know what this BS about having to use Windows 7 is about). The Tech2Win is slightly buggy occasionally, but it’s always been that way. GM crapped that software out most a decade ago.

Dell Lattude E7450 Windows 10 64 bit: works

I have a Dell Lattude E7450 with windows 10 x64 and a touchscreen. I had the same problem as everyone else experienced where it would not pop up the screen to select the MDI. I could get it to popup if I clicked the emulator directly however it crashed since it had no valid params (this is expected by design). I tried many things including the latest Tech2Win and swapping dll files, GM MDI manager versions etc and nothing seemed to work.

In the end the solution came to me and it was quite simple… Went into my device manager, expanded the Human Interface Devices and disabled the touchscreen device. I then could run Tech2Win and the MDI selector popped up like it should. If your device only has a touchscreen you will have to add a keyboard (either wired or Bluetooth) before you disable the touchscreen so you can use Tech2Win.

I’m willing to bet some device that some GM dealerships run the software on are touchscreen (with a compatible Lib) and in windows 10 we have some sort of touchscreen Lib (not compatible) conflict with the application.

Microsoft Surface Pro 4 Windows 10 64 bit: not work

I tested out full functionality of Tech2Win with my older laptop that I just upgraded to 10. It is working and doing what it should.
I also installed it on a desktop with Win10 and it works……

My brand new Surface Pro 4 does have error. It will not work.

Microsoft Surface pro 2 Windows 10 b4 bit: has error

installed tech2win, (vxdiag vcx nano), it works on one laptop but not on another, both laptops are windows 10 x64

GM Tech2:

the one that does not work gives me E668561: Vehicle Communication Interface (e.g. MDI) not found! Is it possibly not installed / not turned on?
The “Select Vehicle Communication Interface” window does not show.
in the log file it shows

Computers with Win 10 updated from Win7 Win8: works good

I have found that the 3 computers that this works on that have Windows 10 were all upgraded from windows 8 or windows 7. There could be something that was carried over that keeps Tech2win working that a Win10 only machine might not have or have set the same. So far I have not found a permissions change that fixes it though. It seems to be something else more elusive.

Toshiba C655: works great

Lenova Yoga 900: not works

Acer Switch 12: not works

Microsoft Surface Pro 4:

For some reason the Surface Pro 4 will just not pop up the screen to select the device when you start Tech2win. It won’t do it in a VM either. The MDI manager will see the MDI fine native or in the VM.

Newer 64bit desktop: works fine

Old 64 bit laptop: works fine

Windows 10 touch screens mobile device: not run

Older Celeron desktop: works fine

(It’s an older Celeron desktop with only 3 gigs of ram that was just upgraded to win10. It works fine on this computer.)


In summary, you need luck with Tech2win Windows 10.

Btw, info not sure but you can have a try:

For windows 10 you need to use the latest Tech2win 2.332
Previous Tech2win 2.322 is not supported from windows 10
