Step 2: Download OpenVPN Community
The Self-Assurance Service Desk will contact you by e-mail when the access has been arranged, and you will receive an attachment with a suffix of .opvn - a file format designed to be opened via OpenVPN.
Important: Please ensure you download the community edition of OpenVPN rather than OpenVPN Connect, otherwise it will not work.
Navigate to the OpenVPN Community Downloads page and select the appropriate version from the available links.
The rest of this guide will cover the Windows 64-bit version.
