Instead of trying to start BTSync as Service, you can run it as scheduled task on system startup. I do this with all applications that don't support running as service and it worked for all I've tested so far. It's much simpler than messing around with srvany. You can start/stop with schtasks.exe, configure it to restart on failure... Actually I don't see a need to run as service anymore @affinity it is, just create two tasks and select different users in the "run as" tab. You will have to log on with these users once to initially setup BTSync
