I know next to nothing about Firebird engine development, but at least in Windows, many applications set a mutex (or other shared structure) that's being checked against in the Uninstaller (like InnoSetup can do automagically for you, Database Workbench is detected as running, for example). I'm unsure how this would work for a specific instance, but perhaps you can keep track of the instance name you used during Service Registration (for multiple instances, like InterBase is doing) and make the Uninstaller check if the service is running? (obviously not the case for test-runs with a command line start). >Another issue with multiple installs is that we would need to update the >gui >to maintain the installs.

On the development machine that I used to install Fb 3.0, there were two instances running, both as an application instead of a service, and the installer responded saying there's an existing server running.
