OpenVPN

ApplicationOpenVPN Inc.

Also called open vpn, openvpn gui, openvpn connect

OpenVPN Inc.Security

The classic userspace VPN. openvpn-gui.exe is the community Windows tray. OpenVPN Connect is the company's other client.

What you need to know

openvpn-gui.exe wants an .ovpn. WireGuard wants a .conf.

OpenVPN is the classic userspace VPN. The community tray is openvpn-gui.exe. Connect is a different official client. WireGuard is a newer protocol. Consumer VPNs hide the profile behind a subscribe button.

What is it?: Classic VPN. GUI wants an .ovpn
Same as WireGuard?: No. Different protocol and file
Same as Connect?: Connect is the other official client

Feex says

If the file ends in ovpn, I would open openvpn-gui.exe, not wireguard.exe. Connect is the other OpenVPN Inc. app if IT said to use that. I would not treat this as NordVPN.

What is OpenVPN?

OpenVPN is a classic VPN protocol. openvpn-gui.exe is the community Windows client. Connect is OpenVPN Inc.'s separate client.

If you have never used it

If someone handed you an .ovpn file, this is OpenVPN, not WireGuard. The community Windows tray is openvpn-gui.exe from community-downloads. OpenVPN Connect is the company's other app. They are not the same installer. You still need a server. This is not NordVPN and not Tailscale.

What is it used for?

Import an .ovpn

IT or a vendor exports this file. WireGuard would have given you a .conf instead.

Community GUI tray

Right-click the tray icon to connect. Connect is a different window from OpenVPN Inc.

Access Server and CloudConnexa

Those are paid OpenVPN Inc. products. The community GUI can still import profiles they export.

Who is it for?

People who were emailed an .ovpn
Admins who still run OpenVPN Access Server
Anyone who should not paste that file into wireguard.exe

Current status

Actively developed. This article is the community Windows GUI plus the protocol, not WireGuard.

How old is it?

OpenVPN dates to 2001. It is the older userspace VPN people still deploy. WireGuard is the newer simple protocol (2018). Current community Windows builds ship the GUI plus openvpn.exe.

Versions

Major channels first. Exact build numbers are not all verified here.

Community GUI

OpenVPN Connect

Access Server (server product)

System requirements

Values follow the publisher's public guidance. Workload still changes the real need.

Minimum

Minimum system requirements
Operating system	Current community Windows builds list Windows 10 and later, per OpenVPN
RAM	Light client. The tunnel is the cost

Resource profile

CPU demand: Userspace encryption while connected
Network demand: Whatever the profile routes

Installed processes

These executables belong to this product when it is installed.

Installed processes
openvpn-gui.exe	Community tray client. Connect is a different app
openvpn.exe	Tunnel process the GUI starts

Startup components

The GUI can sit in the tray. A connection at logon is a profile option, not a Windows service you invent.

File locations

Common OpenVPN locations
Typical install	C:\Program Files\OpenVPN\

File formats

OVPNPKI certs the profile names

Common problems

Connect versus community GUI mix-up

Two OpenVPN Inc. clients. IT usually names one. Installing both is how profiles disappear.

.ovpn imported into WireGuard

Wrong app. WireGuard will not parse OpenVPN directives.

Getting unstuck

Get the community build from openvpn.net/community-downloads

wireguard.com is the other protocol. nordvpn.com is a consumer VPN.

Import the .ovpn into the tray, then Connect from the icon

A silent failure is often a bad path to the config folder.

Ask IT whether they meant Connect

OpenVPN Connect is the paid-product-friendly client. The GUI is the community tray.

Alternatives

WireGuard if you were handed a .conf. Tailscale if you want a mesh. NordVPN if you wanted a country list without a file.

Official help and downloads

Start with the vendor. Random exe sites are not a support channel.

Official contacts
Download	openvpn.net/community-downloads/ Official installer or vendor page
Help	openvpn.net/community-resources/ Vendor support
Official site	openvpn.net/ Start here, not a random exe host
OpenVPN Connect	openvpn.net/client/ Company client. Not the community GUI

Related hardware

OpenVPN uses more CPU than WireGuard on some paths. The server you were given decides latency.
