How do I configure and use OpenVPN with Windows?

To connect to UIC Virtual Private Network (VPN) on a Windows computer, download and install Viscosity from the WebStore. Free of charge for UIC faculty, staff, students, and affiliates.

If you previously installed and used the OpenVPN client, make sure that it is not running. To uninstall it, follow the Windows program uninstallation procedure.

Install Viscosity

Download from the WebStore and double-click on the installer.

Click Yes if prompted “Do you want to install this program”. You may be prompted by your antivirus software or Windows Firewall to allow viscosity.exe to run. Click on Yes and proceed with the installation. If you are prompted with “The publisher could not be verified. Are you sure you want to run this software” hit on Run, or “Do you want the following program from an unknown publisher to make changes to this computer“, click on Yes.
