If you still cannot find the OpenVPN-GUI then make sure you opened it in the first place.

Importing your first connection profile (config file) into the OpenVPN-GUI

Select "Import file ..." from the menu, then select the config.ovpn file you wish to import:


If the import is successful you will see:

Import successful

Otherwise, check that you selected a correctly configured *.ovpn file.

If you do not know what to do then please contact your server's administrator for help.

Additional notes:

  • You should now have a successfully imported configuration file.

Setting up membership of the OpenVPN Administrators local group

In order for your normal user to be able to use openvpn, your user account must be added to the OpenVPN Administrators group on your computer. This is normally done during the install phase but it may not have been done. If you see the message below you can select Yes but you will need the Local Administrator password to continue. If you do not have this password then please contact your network administrator for help.

Message dialogue Require membership in OpenVPN Administrators group

Msg, Require membership of OpenVPN Administrators group

Additional notes:

  • You must now be a member of the Openvpn Administrators group.


  • If you are logged in to your desktop with an Administrator account then this stage will be omitted.

  • You can choose to save the password but the username is always saved.
  • These settings are saved in the Windows Registry under : HKCU\Software\OpenVPN-GUI


Editing the Windows Registry is strongly discouraged .. Do so ONLY AT YOUR OWN RISK!

Common connection problems

When you examine your log file, if this is the only output which you find:

Thu Jul 26 23:51:48 2018 OpenVPN 2.4.6 x86_64-w64-mingw32 [SSL (OpenSSL)] [LZO] [LZ4] [PKCS11] [AEAD] built on Apr 26 2018
Thu Jul 26 23:51:48 2018 Windows version 6.1 (Windows 7) 64bit
Thu Jul 26 23:51:48 2018 library versions: OpenSSL 1.1.0h 27 Mar 2018, LZO 2.10
Enter Management Password:

Then the most likely cause is that OpenVPN has already started the connection profile.
You must ensure that all openvpn.exe processes are terminated and then try again.

The most common cause of this problem is when you use the incorrect OpenVPN Windows services:

Stop and do not use both the OpenVPNService and the OpenVPN Legacy Service Windows services.
Start and do use the OpenVPN Interactive Service Windows service.
