@Yasdnil1966 Just for the record - the problem above has been solved.

The Veyon Service (as called in the MS Services.msc app) had to be started 'Automatically (Delayed)'

Hopefully this will help someone else who see the same issue.

It Worked....
on button start application, when i send a comand like
taskkill /f /im firefox.exe it works.
Thanks for ur help

Since Veyon Configurator is intended to use by administrators only (and requires administrative privileges for changing the configuration and performing related operations), there's no way to run the program without administrator rights. You have to enter the name and password of an administrator account and then you should be able to start Veyon Configurator.

You have to setup the bios of PCs and to turn Wake on Lan on (and to provide mac address for every PC in the veyon configer.) https://www.google.com/search?q=bios+wake+on+lan

I had the same problem, but that happend, when I didn't provided IP for the PC

Sorry no to answer earlier, I think this summer I missed the notification of your reply.

I will run the veyon-master manually at school tomorrow to give a try.

The users home directory is located on an NFS server. The home directory is automatically mounted at connection with autofs.
