Software V2021 not working after update the OS from Win10 to Win11

PC-DMIS cannot read the file C:\PCDMIS\PONTAS\xxxxxx.PRB. It can happen for many reasons: it could be corrupted or could be created in an updated version. It could be created in an old version not supported. The updated version is 2015.1.

And we have version 2019 and 2021 installed on that PC.

OK, it could be because Windows 11 changed permissions on that folder.  I assume you've verified that the folder and the file exists, and it is larger than 1 MB.  I think the easiest solution might be to recreate that probe file and calibrate it, then see if it helps.  Of course if you store it in the same location you will need to check the permissions.
