If you are not using the MPN OpenVPN application on your system anymore or if you are encountering errors with the current installed version, we suggest you uninstall it following the steps below:
1) Go to Control Panel > Programs > Uninstall a program
2) Select the OpenVPN installation and click on Uninstall / Change
3) Click on Uninstall
4) Click on Next > Finish to complete the Un-installation process.
In some cases, you might still have issues reinstalling the application as some of the files and registry entries are not fully removed from the system.
To be sure, you can manually remove them by following the steps below:
1) Delete the OpenVPN folder from the installed directory. By default, the OpenVPN application will be installed under this folder:
32bit systems - C:\Program Files\OpenVPN\
2) Download the OpenVPN registry removal script here:

3) Launch the registry file that you've downloaded and follow through the process to complete the removal.
