I already encountered the same issue in a different context. The problem occurs also when you try to run the simulation, or connect to a PLC with encrypted communication.

I assume it is a bigger task, but I believe the clean solution is to implement ncrypt in wine.

Googling for it, turned out, that there was a fix in this region recently:

The microsoft installer was the driving force for that.

Maybe you want to try this new wine version?

I am already very curious, if it works now...
