Hello,
I have purchased Miltech Mission Hub through Contrail and I am using Microsoft Flight Simulator 2024 (Steam version).
The Mission Hub installs correctly and appears as installed in Contrail.
I can open Mission Hub inside MSFS 2024, create a mission, edit it and save it successfully.
However, every time I press Save & Play, I receive the following error:
WASM Error: Package files have not been copied yet. Cannot start scenario.
Information:
MSFS 2024 (Steam)
Mission Hub v1.2.2
Installed through Contrail
The WASM package files exist in the installation folder.
Contrail remains open while MSFS is running.
Restarting both Contrail and MSFS does not solve the problem.
The mission is saved correctly but cannot be started because of the WASM error.
Could you please tell me:
What package files are missing?
Where should they be copied?
Is there an additional installation or activation step required for the WASM package?
Thank you very much.
Miltech Simulations @MiltechSimulationsGo to %appdata%\Microsoft Flight Simulator 2024\WASM\MSFS2024, right click the 'miltechsimulations-missionhub' folder and select Properties.
In the popup window, make sure 'Read-only' is unchecked. Click apply. If there is another pop-up, select 'Apply changes to this folder, subfolders, and files'.Then restart your PC, and relaunch MSFS. Should work!

I followed your instructions exactly. I removed the Read-only attribute, applied the changes to the folder, subfolders and files, restarted Windows and MSFS 2024, but the problem remains unchanged. The error is still: "Package files have not been copied yet. Cannot start scenario."
Could you tell me which package files Mission Hub expects to copy, and where they should be copied?
Miltech Simulations @MiltechSimulationsNo files need to be copied manually. Copying process occurs automatically, provided that Mission Hub has full write access.
You may try to delete completely the folder:
%appdata%\Microsoft Flight Simulator 2024\WASM\MSFS2024\miltechsimulations-missionhubDeleting this folder and re-launching the sim will force Mission Hub to re-build the folder and copy the files again. The write attribute should stay. Please give this a try and let me know if it works.

I followed all your instructions.
Deleted the miltechsimulations-missionhub WASM folder.
MSFS recreated it successfully.
The WASM files (.dll, .lib, .obj, .cache) are present.
Mission Hub opens correctly.
I can create and save a mission (entrenamiento.json is saved in work\SavedScenarioFiles).
InstalledPackagesPath is correctly configured.However, when I click Save & Play, Mission Hub reports:
"WASM Error: Package files have not been copied yet. Cannot start scenario."
I also checked the Packages\Community folder and no new mission package is created or copied there.
Could you please tell me which package should be created, where it should be copied, or whether there is a known issue with this step?
