John Dowson Posted 1 hour ago Report Posted 1 hour ago By "switching off", do you mean that FSUIPC exited? You log file shows that FSUIPC was running for just under 6 hours and then exited as MSFS was no longer running. If MSFS was still running, you can try setting the DisableMSFSMonitor ini parameter to Enum or Yes. From the Advanced User guide: Quote DisableMSFSMonitor: this disables FSUIPC's MSFS (window) monitor, which disconnects (and possibly closes) FSUIPC when MSFS can not be found. Some users have reported this issue on Windows 11, with FSUIPC7 closing (or repeatedly disconnecting) even though MSFS is still running. Setting this option to Enum can prevent this issue by using a different method (window enumeration) to find MSFS, and setting to Yes will disable the MSFS monitor. As of FSUIPC version 7.3.7 (and later), windows 11 should be detected and this option automatically set to Enum, although you can still override this by explicitly setting this parameter in your FSUIPC7.ini.
