Addons Not Detected, AIRAC Unable to Update

I am an X-Plane 12 user who is attempting to load my SimBrief flight plans into the aircrafts’ FMS for airliner flights. However, I am unabme to update my AIRAC cycles, which causes the error “AIRAC CYCLE MISMATCH” in the FMC, and my flight plans unable to load into X-Plane.

I tried using FMS Data Manager to update the AIRAC cycles in X-Plane, but I was unable to, as X-Plane (or any mods I use) remain undetected by the system.

A “complete” scan yields no results.

Attempting to manually add an addon yields no results.

I have attempted many fixes as suggested by the forum, all to no avail. The methods include:

  1. Uninstalling and reinstalling FMS Data Manager, together with logging out and into Navigraph.

  2. Restarting my PC.

  3. Downloading the manual navigation updates for both X-Plane 12 and FlightFactor B777 (the aircraft I am using), and extracting them to the “Custom Data” folder.

  4. Checking that all my mods and X-Plane, and the FMS Data Manager, are updated to their latest versions.

  5. Closing X-Plane 12 while carrying out the process.

  6. Double-checking the path of X-Plane in my computer, as shown in the screenshot below.

I have tried many methods, but still my AIRAC remains not updated in X-Plane. Please advise on how I may rectify this issue.

Hi Kevin,

Welcome.

In FMS Data Manager Settings, check that your x-plane.exe is in the folder D:\X-plane 12. Press Save .

In Addon Mappings, manually +Add entry X-Plane 12, with Install into X-Plane 12.

Do the same for X-Plane 12 add-ons. Press Save.

In Addon List, select and update X-Plane 12 and X-Plane 12 addons.

Cheers

Ian

Hi Ian, thank you for the suggested solution. I have attempted the fix but got stuck at the “Addon Mappings” step; they simply do not allow me to add an addon manually unless it has been detected by the system, which strangely shows none.

I have confirmed that xplane has always been under the specified folder and saved it.

This is what happens after I press Add (see left dropdown menu: “Please select an addon”).

Please advise.

When you Install into… choose User Defined folder and navigate to the folder where you have X-Plane.exe

Cheers

Ian

Hi Ian,

Thanks for the reply and help once again. Unfortunately, nothing happens when I click “Install Into”…there is no drop down menu or anything.

Cheers and please advise.

Hi,
You can also try uninstalling the FMS Data Manager. After that, reboot your PC. Then open the file explorer and copy&paste this %programdata%\Navigraph\FMSClient

Delete all files and subfolders, if they exist.

After that, reinstall the latest version of the FMS Data Manager and try it again. Furthermore, could you please upload the x-plane_install_12.txt file? You find it here %localappdata% (again, copy&paste it in the file explorer).

Thank you very much,
Richard

Hi Richard,

Thank you for the guidance. I will try that now. Just for clarification, what do you mean by “uploading” the “x-plane_install_12.txt” file? On this forum?

Drag and drop the file in your posting, and it will be uploaded :wink:

Thanks for your help and also your patience
Richard

Here is the file, thank you.

Dear Richard and Ian,

Thank you so much for the assistance! The issue seems to be resolved for now - I can add and update X-Plane with all of its addons.

Have a good day!
