Windows ARM64 installers

Our MSI installer do not currently support the Windows ARM64 platform. You need to use our NSI-based snapshot installers from here. We recommend using the latest installer that matches one of these patterns:

• openvpn-install-2.5_git-I900-release-2.5-* (stable 2.5 version)
• openvpn-install-2.6_git-I900-master-* (development version)

OpenVPN 2.4.10 — Released 9 December, 2020

This is primarily a maintenance release with bugfixes and small improvements. Windows installers include the latest OpenSSL version (1.1.1i) which includes security fixes.

A summary of the changes is available in Changes.rst, and a full list of changes is available here.

Please note that LibreSSL is not a supported crypto backend. We accept patches and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions of LibreSSL break API compatibility we do not take responsibility to fix that.

Also note that Windows installers have been built with NSIS version that has been patched against several NSIS installer code execution and privilege escalation problems. Based on our testing, though, older Windows versions such as Windows 7 might not benefit from these fixes. We thus strongly encourage you to always move NSIS installers to a non-user-writeable location before running them.

Please note that OpenVPN 2.4 installers will not work on Windows XP. The last OpenVPN version that supports Windows XP is 2.3.18, which is downloadable as 32-bit and 64-bit versions.

If you find a bug in this release, please file a bug report to our Trac bug tracker. In uncertain cases please contact our developers first, either using the openvpn-devel mailinglist or the developer IRC channel (#openvpn-devel at irc.freenode.net). For generic help take a look at our official documentation, wiki, forums, openvpn-users mailing list and user IRC channel (#openvpn at irc.freenode.net).

Important: you will need to use the correct installer for your operating system. The Windows 10 installer works on Windows 10 and Windows Server 2016/2019. The Windows 7 installer will work on Windows 7/8/8.1/Server 2012r2. This is because of Microsoft’s driver signing requirements are different for kernel-mode devices drivers, which in our case affects OpenVPN’s tap driver (tap-windows6).

This release is also available in our own software repositories for Debian and Ubuntu, Supported architectures are i386 and amd64. For details. look here.

The Windows installers are bundled with OpenVPN-GUI – its source code is available on its project page and as tarballs on our alternative download server.

OpenVPN 2.4.9 — Released 17 April, 2020

This is primarily a maintenance release with bugfixes and improvements. This release also fixes a security issue (CVE-2020-11810, trac #1272) which allows disrupting service of a freshly connected client that has not yet not negotiated session keys. The vulnerability cannot be used to inject or steal VPN traffic.

A summary of the changes is available in Changes.rst, and a full list of changes is available here.

Please note that LibreSSL is not a supported crypto backend. We accept patches and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions of LibreSSL break API compatibility we do not take responsibility to fix that.

Also note that Windows installers have been built with NSIS version that has been patched against several NSIS installer code execution and privilege escalation problems. Based on our testing, though, older Windows versions such as Windows 7 might not benefit from these fixes. We thus strongly encourage you to always move NSIS installers to a non-user-writeable location before running them. We are moving to MSI installers in OpenVPN 2.5, but OpenVPN 2.4.x will remain NSIS-only.

Compared to OpenVPN 2.3 this is a major update with a large number of new features, improvements and fixes. Some of the major features are AEAD (GCM) cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack support and more seamless connection migration when client’s IP address changes (Peer-ID). Also, the new –tls-crypt feature can be used to increase users’ connection privacy.

OpenVPN GUI bundled with the Windows installer has a large number of new features compared to the one bundled with OpenVPN 2.3. One of major features is the ability to run OpenVPN GUI without administrator privileges. For full details, see the changelog. The new OpenVPN GUI features are documented here.

Please note that OpenVPN 2.4 installers will not work on Windows XP. The last OpenVPN version that supports Windows XP is 2.3.18, which is downloadable as 32-bit and 64-bit versions.

OpenVPN 2.4.8 — Released 31 October, 2019

This is primarily a maintenance release with bugfixes and improvements. The Windows installers (I601) have several improvements compared to the previous release:

• New tap-windows6 driver (9.24.2) which fixes some suspend and resume issues
• Latest OpenVPN-GUI
• Considerable performance boost due to new compiler optimization flags

OpenVPN 2.4.7 — Released 21 February, 2019

This is primarily a maintenance release with bugfixes and improvements. One of the big things is enhanced TLS 1.3 support. A summary of the changes is available in Changes.rst, and a full list of changes is available here.

Please note that LibreSSL is not a supported crypto backend. We accept patches and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions of LibreSSL break API compatibility we do not take responsibility to fix that.

Important: you will need to use the correct installer for your operating system. The Windows 10 installer will not work on Windows 7/8/8.1/Server 2012r2. This is because Microsoft’s driver signing requirements and tap-windows6. For the same reason you need to use an older installer with Windows Server 2016. This older installer has a local privilege escalation vulnerability issue which we cannot resolve for Windows Server 2016 until tap-windows6 passes the HLK test suite on that platform. In the meanwhile we recommend Windows Server 2016 users to avoid installing OpenVPN/tap-windows6 driver on hosts where all users can’t be trusted. Users of Windows 7-10 and Server 2012r2 are recommended to update to latest installers as soon as possible.

OpenVPN 2.4.6 — Released 24 April, 2018

This is primarily a maintenance release with minor bugfixes and improvements, and one security relevant fix for the Windows Interactive Service. Windows installer includes updated OpenVPN GUI and OpenSSL. Installer I601 included tap-windows6 driver 9.22.1 which had one security fix and dropped Windows Vista support. However, in installer I602 we had to revert back to tap-windows 9.21.2 due to driver getting reject on freshly installed Windows 10 rev 1607 and later when Secure Boot was enabled. The failure was due to the new, more strict driver signing requirements. The 9.22.1 version of the driver is in the process of getting approved and signed by Microsoft and will be bundled in an upcoming Windows installer.

Please note that LibreSSL is not a supported crypto backend. We accept patches and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions of LibreSSL break API compatibility we do not take responsibility to fix that.

Also note that Windows installers have been built with NSIS version that has been patched against several NSIS installer code execution and privilege escalation problems. Based on our testing, though, older Windows versions such as Windows 7 might not benefit from these fixes. We thus strongly encourage you to always move NSIS installers to a non-user-writeable location before running them. Our long-term plan is to migrate to using MSI installers instead.

Compared to OpenVPN 2.3 this is a major update with a large number of new features, improvements and fixes. Some of the major features are AEAD (GCM) cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack support and more seamless connection migration when client’s IP address changes (Peer-ID). Also, the new –tls-crypt feature can be used to increase users’ connection privacy.
