Yes I tried with the "OpenVPNManager GUI" checkbox option.
And it seems to run as a service and it works around the UAC control as far as I can see that with the few tests I did.
And it still allows different OpenVPN configs so you are able to select them from the new/different GUI - but they all must be in the new folder path and they must not be in a subfolder and so - of course - must have different filenames for .key, .p12 and .ovpn.
If the config is in the new path it seems that it will be run as a service and if it is in the "old" path it will run "normal".
Configs in both paths are possible.
At least it seems to work and the new features and the slightly different behaviour in GUI will need some time to test but is probably a good possibility to use. :)
