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.

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\
