Hi, i am unable to start MES on Windows 11 ARM64 anymore.
After one of the last updates it stoped working and crashes while starting.

Is there any solution?

I was using v5.3 on my MacBookPro M1 win11 Parallels almost a year with no problem. Updated to 5.4 no problems until sometime in December when it just no longer starts. Tried to reinstal but installation is not starting just dies. Something with .net framework but it is up to date, Parallels updated, Win11 updated. Could not move to another machine as it was not starting so no way to retrieve deactivation code. No choice so I paid for new licence (again) and istalled on my sons lpatop. Still looking for soultion … :(

ChatGPT told me that MES is using .Net Framework 2 or 3.5 and that the developer should use a newer version.
@MES developers, could you please double check that and provide a working solution?
As an alternative i bought an Apple ios licence and using it on my mobile, but thats not the same, dont like it that way.

Io ho installato la versione 5.2 gratuita (demo) per capire se sarei in grado di usarlo, ma non si avvia non dà nessun segno di vita dopo l’istallazione non è compatibile con Windows 11? Ho aggiornato anche framework e Studio C più più
