Openvpn 2.4 uses the new
Interactive service
so the user does not require Administrator privileges to use openvpn.
This is a bit out of date but gives the overall gist.
If you have installed 2.4 and the
interactive service is running your user should be able to use openvpn.
You may need to add the user to a new Windows group called "Openvpn Administrators".
This group is
only used to verify that the user is allowed to use openvpn interactive service,
it does
not confer any administrative privileges to users in the group.
