Bingo - charger was the problem. Very much appreciated Azzuro!

Thanks - shall unplug the charger and see that difference that makes.

Howdy folks, hoping this channel is still monitored.

I have Version 1.0.2.1 and I'm trying to run it on W10 Pro (21H2).

I've the latest Peak drivers (4.4.0.16619).

Process I'm following is to plug in and connect the peak interface to an old VX-1(NiMh firmware) with ignition off.

I'm then opening VDiag before turning on the ignition.

Once the software opens it, naturally comes up without an active canbus and is stable, navigable, and appears to do what it should.

As soon as I turn on the ignition however, I get to see the Canbus go active, most of the red turns to green, and then the software exits with no debug terminal or anything. It just shuts down.

I've tried running in compatibility mode all the way back to XP-SP3 and the behaviour remains consistent.

Any suggestions?

Cheers,
