[Solved] PFC MCP not working

Selkan · 2026-07-20T13:26:58Z

Hope I'm in the right place for some advice as I am running FSX. I have recently had a new PC running Windows 11 Home. I have a Precision Flight Controls MCP (Hardware) in my Boeing 737 Cockpit. I have two Com Ports; one connected to PFC Jet Liner Console (Com Port 4) and working fine. Latest FSUIPC installed with Wide Server/Client and registered. My MCP is connected to Com Port 3. Build 544 (latest Build) installed from Project Magenta. Com Port 3 detailed/added to MCP ini file. All Folders Shared etc. I simply can not get my MCP to interact with FSX. On my main screen MCP is shown (2D) when starting program, and that is interacting with FSX as knobs, switches etc are all working. Any advice much appreciated. I have looked at logs, but very little information available.

Hi, problem solved!!! As I think you know John I have a new PC running Windows 11. Prior to this was using Windows 7. The whole problem relates to 'saving' changes in MCP ini file. As you will know, under Windows 7, you would make a change, click close, and up would come a window asking if you wanted to Save the change. Click Save and end of.

It would seem very different in W11. Make change in ini file, click file - save - up comes window asking if you want to save which would replace the whole ini file being used. Clicking yes does not save the file!, at least not for me.

We ended up copying the ini file to the desk top, making the necessary changes, particularly Com Port 3, and placing back in MCP Folder and overwriting existing file. Having done this my MCP fired up.

I hope anyone following all of this has learnt something to help them. I would thank you very much John for the time you have devoted to this one. My kind regards to your Dad; without him we wouldn't even have been having these talks.

Very best, Steven

Great - glad you got to the bottom of this! Strange though - maybe it is a permissions issue on the ini file or one of the folders its under?

No problem - will pass on your regars, cheers,

John
