Ista+ 4.39.20 and VCX SE programming

[Vinz]

I’ve seen this being discussed in the past and have seen people report it’s an issue with 4.39.20 and no issues with prior versions.

Your best bet will be to wait for a driver update from VCX and try an older ISTA+ versions in the meanwhile!

You can use whichever PSdZData you have or desire with an earlier ISTA version.

Try to enable VCX logging and post the log? It may give us a clue of why it’s failing.
