Correction to my previous post : should say

"We tested our latest version 4.06 in Windows 11 Pro ARM 23H2 under Parallels Desktop 19.3.1 running on Apple 2023 Mac mini with Apple M2 ARM CPU and this works just fine together with Surfer 11 and CodeMeter USB dongle."

We tested our Pro version 4.06 software using up to 8 CPU cores on Apple 2023 Mac mini with ARM CPU. 4.06 Standard can use up to 4 CPU cores for WET inversion only.

This does not work on Apple M2 ARM CPU when using the green WibuKey USB dongle.
