[Solved] PMDG 737 MSFS 2024 – FMC Origin/Destination uitlezen via FSUIPC7 offsets
Hello John,
Following up on the WASM issue, I have attached a ZIP containing the installation log and the latest FSUIPC7 log.
The installer reports that the WASM module was successfully installed in the MSFS 2024 Community folder. We checked that this matches the InstalledPackagesPath in UserCfg.opt. The module files are present, and FSUIPC7_WASM.wasm is exactly 1,932,979 bytes, matching layout.json.
After fully closing and restarting MSFS 2024, FSUIPC still reports:
“FSUIPC WASM module not detected - not adding WASM menu”.
The PMDG data and CDU reading do work. We also noticed that, after restarting only FSUIPC during a loaded flight, the CDU test returned empty screens with POWERED=0. Switching the left CDU from RTE to LEGS and back restored the data, including EHGG and EHAM.
Could you please check the logs and advise on the next step for the WASM detection issue?
Many thanks for your help.
Kind regards,
Mente

So it looks like the data is only initially available once it has been changed/updated. Not sure why this would be, but I don' think there is much that can be done about this, but I will look into it to see if I can read the data initially before any update callbacks are received.
For the WASM, as I previously said - does the following file exist:
C:\Users\Mente Holwerda\AppData\Local\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalCache\Packages\Community\fsuipc-lvar-module\layout.json
?
FSUIPC7 checks for the existence of this file, and if not present, it thinks the WASM isn't installed. If the file does exist, check the access permissions on this file. Your installation log indicates that this file does exist, so its either a permissions issue or possibly a problem with you having a space in your user account name 'Mente Holwerda', but this shouldn't be a problem really...
And if you ran the FSUIPC7 installer with admin privileges, please uninstall and re-install with standard privileges and try agaiin.
Hi John,
Thank you for looking into this.
I can confirm that layout.json exists at the exact path you specified. I checked the Security tab for both the file and its containing folder: my account, “Mente Holwerda”, has Full Control, including read access, with no Deny permissions shown. The file also opens normally in Notepad.
I did not explicitly launch the FSUIPC7 installer using “Run as administrator”. I cannot confirm whether Windows requested elevation during installation.
Your last sentence appears to be incomplete: “And if you ran the FSUIPC7 installer with admin privileges, please...” Could you clarify what you wanted me to check?
Regarding the CDU data, switching away from the page and back makes the data available, consistent with your findings.
Kind regards,
Mente

It does.

Hmm...looks complete to me: "And if you ran the FSUIPC7 installer with admin privileges, please uninstall and re-install with standard privileges and try again.". But forget this!
Looks like it checks that file for read-access only, so it will fail if you have other permissions. Not ideal. I have changed this in the attached version if you could try it.

Hi John,
I replaced FSUIPC7.exe with your attached version and restarted FSUIPC7 while MSFS 2024 remained running. The log confirms version 7.5.10b, but the WASM menu is still missing and it still reports:
“FSUIPC WASM module not detected - not adding WASM menu”
I have attached the new log. As checked earlier, layout.json exists at the exact path you specified, my account has Full Control, and I can open the file normally in Notepad.
Kind regards,
Mente
