problems with the use of Veyon

[tmartinez]

Good I have configured Veyon in about 30 computers, are connected to a domain but in the configuration I used the key file
The first problems that I find are that when I restart the PCs in the classrooms, the Veyon service is disabled, I check it in services.msc.
At the same time I have VNC installed on the PCs but their service is disabled a priori
Create a class and add 30 PCs when I import the configuration into another PC the master.exe gives error and quits. It does not happen when I create the database from the master computer that will be used

Which version of Veyon are you running? Which VNC software do you have installed? Can you take a look at the log files in C:\Windows\Temp\Veyon*log ?
