Answer 1

I found out the solution which is disabling the git PATH used where as it puts the version of gpg.exe shipped with git ahead of the one from openvpn package on my environment variables.
This could be done in two ways;
The first is editing the environment PATH variables and moving git PATH below the C:\Program Files (x86)\GNU\GnuPG\pub PATH, see the picture below.
The second is removing/deleting the git PATH variables then start a new powershell session, run choco install openvpn then returning the git PATH back to the env variables.
In my case, the fist option worked just fine.
