BMW ICOM A2 software error “Failed to start ISTA” (solved)

When I enabled coding/programming in BMW ICOM A2 diagnostic software ISTAD, just for comfort reasons, all in one, but unluckily, the error message popped up as follows:


Failed to start ISTA.

Please make sure your ISTA configuration is valid.

In doubt reset any non standard ISTA configuration and reinstall ISTA


Searched lots of info online and finally SOLVED! ISTA+ works like a charm!


Just add this to the configuration file:
<add key=”BMW.Rheingold.Programming.PsdzBackupDataPath” value=”%ISPIDATA%\BMW\ISPI\data\TRIC\ISTA\Temp\”/>
