@Fiat Lux - ASIA I can get QBDT to run on the Windows 11 Pro machine, but two of our Windows 10 Pro machines can't access the Windows 11 machine, although the 3rd one can. That machine can open the file and write to it, but the other 2 machines get a "you do not have permission to access this networked comptuer" message ("the machine appears to be configured correctly, but the computer is not responding"). All three are set up in exactly the same way, so not sure what the problem is. I will suggest they downgrade to Windows 10, I guess. Sad.
