I’m currently packaging the 2026 version of FlightStream for deployment in our labs. During testing, the application reports that it cannot obtain a license because the server version is older than the application version.

When attempting to install the 2026 version of the Altair Licensing Utility on the license server (which is currently running version 2025), I encounter an error. Running the installer (altair_licensing_2026.0.win64_x64.exe) consistently produces the error shown above.

I’ve tried installing version 2026 over the existing 2025 installation, as well as uninstalling version 2025 first and then installing 2026, but the same error persists in both cases. However, when I test the installer on a VM, it installs successfully without any issues.
