Floating License Server Help

Fails during the restart step


MSI-based Floating License Server installer fails during the restart step.


FLS creates a dedicated user to run the application. New versions’ installation may fail during the attempt of application restart.

The reason is in permissions’ conflict between the JetBrainsLS users (see screenshots for reference). It’s likely to happen with build #5374 and older.

Restart old windows

To solve the issue, stop and uninstall the application using Windows standard tools of Control Panel + delete related folders from %programData% and %userprofile%.

Uninstall old server

After that, repeat the installation of the new version.
