On two dual-boot Windows 10 and Ubuntu 24.04 LTS PC’s, Proton VPN no longer works once OpenVPN Connect has been installed on Windows OS, due to a conflict in resources. However, either works well when both are installed on Ubuntu without issue. (Though I’ve not attempted using them simultaneously.)
Note that the error message states, “To fix it, close [it is closed! ed.] or uninstall the app… TAP-Windows Adapter V9 for OpenVPN.”
What I’ve tried to get them both working on Windows, to no effect:
- Updating both applications to the latest versions.
- Stopping two OpenVPN services,
agent_ovpnconnectandovpnhelper_service. - Ensuring that no OpenVPN executable is running.
Yes, I realize the two versions of Proton VPN are very different, not only in the user interface, but also in the underpinnings. Ubuntu also has built-in support for OpenVPN, whereas Windows does not. And admittedly, there is no pressing reason to have both working, since either serves the purpose.
That said, it would be nice to have an alternate VPN, should there be issues with one.
Is there some way to get them to coexist on Windows?
