MSIX works on Windows 11 but not 10

Hi WaterPigeon,

you can try to add the webengineprocess.exe executable to the AllowAllTrustedApps registry key.

This is the least invasive solution and will allow the MSIX package to work on both Windows 10 and Windows 11.

To add the webengineprocess.exe executable to the AllowAllTrustedApps registry key, follow these steps:

1. Open the Registry Editor.
2. Navigate to the following key:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModel\AllowAllTrustedApps

1. Right-click on the AllowAllTrustedApps key and select New > String Value.
2. Enter the following name for the new string value:

webengineprocess.exe

1. Double-click on the new string value and enter the full path to the webengineprocess.exe executable in the Value data field.
2. Click OK to save your changes.

Once you have added the webengineprocess.exe executable to the AllowAllTrustedApps registry key, you should be able to install and run the MSIX package on both Windows 10 and Windows 11.
