    I tried to start a mission with the hpg 145 and I keep getting this error, I tried reinstalling, restarting, read only option is on blue but it doesn't deactivate, it just turn on again by itself, I have no clue what else I can try

        1. Locate the WASM Folder
          MSFS2024 Steam
          %appdata%\Microsoft Flight Simulator 2024\WASM\MSFS2024\miltechsimulations-missionhub
          MSFS2024 Store
          %localappdata%\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalState\WASM\MSFS2024\miltechsimulations-missionhub

        2. Right click the 'miltechsimulations-missionhub' folder and select Properties.

        3. 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'.

        4. Then restart your PC, and relaunch MSFS. Should work!

            Maybe windows is blocking it?, it always appears as read only, no matter how I try to uncheck it I 'll keep trying that method, thanks

                I also cannot unselect read-only.

                    Do you have full administrator rights to your PC? It may be Windows blocking the action due to insufficient permissions.

                    You may need to take ownership of the folder, then disable Read-only: https://www.youtube.com/watch?v=YWgDDip5Bqo

                    This is unfortunately Windows blocking access to the folder, so Mission Hub is unable to function correctly as it cannot write files.
