IPC Sendmessage failed all retries from UIPC_SDK_C

[Amadeus]

Hello,

before with P3D i was doing application that using the FSUIPC SDK (in C) to connect my app.

With Msfs2020, i'm not able to connect my app to the FSUIPC. 

I'm getting the error IPC Sendmessage failed all retries.

And this even if i'm using the standars UIPChello demo that come in the SDK.

 

What does as change and is there a link by the fact that FSUIPC is not embedded anymore?

 

Thank you for your help

Daniel

No. The most likely reason is that you are running MSFS and FSUIPC "as administrator", but not your FSUIPC application (or vice versa). Any FSUIPC client needs to be on the same privilege level as FSUIPC or they cannot communicate.

This has always been the case, it is no different with MSFS.
