Can't install on Win10 Clients

[MrBitey]

Hi all
I'm trying to upgrade my Win10 Education (1703) clients from 4.1.2.0 to 4.3.2.0
The installer does not run. Just a flicker of an hourglass but that's it.
I'm logged in as admin and have tried 'run as administrator' but no luck.
I've tried uninstalling 4.1.2.0 first. Didn't help either.

Any suggestions as to what I might try?

Try using the free version of PDQ Deploy, I was able to deploy the Veyon 4.3.3.exe to 30 computers, its really simple to use. When deploying just add the following parameters for a silent install and remove Veyon Master:

/S /NoMaster
