Install OpenVPN using Group Policy

[Snailkhan]

Hi
I have openvpn setup in pfsens, i want to deploy it to some 50 plus users machines. they do not have admin rights and are in domain.

Is it possible to install it using group policy ?
Really appreciate if someone can share some doc related to it.

Regards

@Snailkhan Sure. Just grab the .msi installer and deploy it with GPO, or like I do with a Powershell script that calls msiexec /qn
