FSUIPC7 is stuck at "Starting everything now"

[Djeez]

When starting FSUIPC and watching the log, I see that it gets stuck at the "starting everything now" message. When viewing the LVars from the FSUIPC UI, I get 0 LVars and 0 HVars loaded. I checked that the fsuipc-lvar-module folder is present in the community folder. I also tried with different aircraft and removed the fsuipc.ini file to have it recreated from scratch. Nothing helps. Can you help me debug this issue?

Attached is one of the typical log files.

Thanks!

Your log file looks very strange... What state is MSFS2024 in when FSUIPC7 is started? Usually it is started while MSFS is still loading, but your log seems to indicate that an aircraft was already loaded and ready-to -fly.
What happens if you exit FSUIPC7 and then restart it?

Could you also please set WAPI Debug logging (Log->WAPI->Debug), and add offset logging (Log->Offsetts...) for offset 026D as U8.
Then show me another log with that logging, and also exit an restart FSUIPC7 and show me a log file from that.

Hi,

I tried several starts and FSUIPC restarts, all with the same effect (I am not sure from what session the log file was that I sent you). 

Here are more log files, copied at different phases during MSFS2024 startup. There is also one with additional logging enabled, from starting MSFS2024 until ready to fly on the runway.

Your logs show that FSUIPC7 is waiting for the WASM. Can you:
   1. Check to see if the WASM is running. You need to enable the developer tools in MSFS to do this.
       Once you have enabled the MSFS developer tools, go to Debug -> Display WASM Debug menu,
       and then select the FSUIPC WASM module from the menu, and go to the Module Section tab.
       What do you see? Can you take a screenshot. It should look like this:

   Maybe also a screenshot of the Wasm Section tab.

  2. Show me / attach your FSUIPC_WASM.log file. If you don't know where this is, take a look at the WASM section in the Advanced User guide.
      It may also be a good idea to set Debug level logging in the WASM (via the FSUIPC_WASM.ini file LogLevel entry), also explained in that section.

In the WASM Debug dialog I can only select fcr-embedded in the Modules dropdown, so I can not select fsuipc-lvar-module to have a look at the Module Section.

I changed the FSUIPC_WASM.ini file to set the LogLevel to Debug but that did not change the log file: it is still from July!

So this would indicate that the FSUIPC WASM module is not running, which will be your issue.

The FSUIPC_WASM.log file you attached is also very old - from 30th July.

Could you please show me your InstallFSUIPC7.log file, and can you confirm that you are using an MS Store version of MSFS2024, and not Steam.

Also, do you see the FSUIPC WASM installed under:
    C:\Users\aegva\AppData\Local\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalState\WASM\MSFS2020\fsuipc-lvar-module

?

[Djeez]

Yes, it is MSFS2024 Windows Store edition, and yes, the folder you describe is present. I will add a screenshot of its contents.

I gathered the information you asked for and some more files and screenshots that hopefully can give you some clue.

The mystery of the July version of the WASM log is somewhat cleared up because I saw another FSUIPC folder at another location where FSUIPC was previously installed. Those files were dated July 2025 so maybe at that time that version has worked correctly.

The FSUIPC WASM module is installed in your MSFS2024 Community folder, which is here:
    C:\Users\aegva\AppData\Local\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalCache\Packages\Community\
...or at least FSUIPC thinks it is...

This looks like a strange location to me, as it is under LocalCache. What else is installed under that folder? Is there an 'fcr-embedded' folder? If not, where is that installed? Where do you think your MSFS2024 community folder is?

Could you show me / attach your UserCfg.opt:
    C:\Users\aegva\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalCache\UserCfg.opt
The Community folder is taken from the InstalledPackagesPath location specified in that file.

Your MSFS2020 community folder is C:\MSFS2020\Community\, which is a lot better...
