Keyman for Windows Alpha now has native support for Windows on ARM (ARM64). With this release Keyman will run with native ARM applications on Windows 11 ARM devices.
This support will be included in the official Version 19 release, scheduled for late 2026.
Installation
If a previous version of Keyman is already installed that does not support native ARM applications (any version less than 19.0.182), it will first need to be uninstalled. You can then install the latest Alpha from https://keyman.com/downloads/pre-release/.
Alpha version 19.0.182 or later supports Windows 11 on ARM.
Previous Versions
“I thought I had a previous version of Keyman partially running on my ARM-based Windows device?”
Windows on ARM devices can run applications built for 32-bit (x86) and 64-bit (x64/amd64) architectures. These applications may work with older versions of Keyman, but this configuration is not officially supported.
Microsoft App Assure
Microsoft, through their App Assure program, supported the development of Keyman’s ARM compatibily through donation of computer hardware for testing.
