Where to find logs for failed msix installation?


Situation

We created and signed a MSIX package of our .NET MAUI app for distribution outside MS Store and Installation with App-Installer.

Problem

While (up to now) most of testing users don`t have any problems with installation with MS App-Installer, in one case installation fails showing this message: "App Installer failed to install package dependencies. Ask the developer for -package[!]."

Tries

Because I don't have a clue, what package exactly could be missing, I searched for some error logs / error codes in Event Viewer (here: Application and Services Logs -> Microsoft -> Windows -> AppxDeployment-Server), following these instructions , but could not find anything in AppxDeployment-Server.

Could anyone please tell me, where else to find logs for failed msix installation? Or does maybe anyone could give me a suggestion, what could be the reason for the failing installation?


Solution

  • We found a solution that works in our context:

    • <WindowsAppSDKSelfContained>true</WindowsAppSDKSelfContained> and
    • <Target Name="_RemoveFrameworkReferences" BeforeTargets="_ConvertItems;>_CalculateInputsForGenerateCurrentProjectAppxManifest"> <ItemGroup> <FrameworkSdkReference Remove="@(FrameworkSdkReference)" Condition="$([System.String]::Copy('%(FrameworkSdkReference.SDKName)').StartsWith('Microsoft.WindowsAppRuntime.'))" /> </ItemGroup> </Target>

    as described here. Unfortunaley this causes a error "The platform 'AnyCPU' is not supported for Self Contained mode" so we had to add "-p:Platform=... option to our dotnet publish command as described here. For being able to start our program in VS we also had to add <Platforms>AnyCPU;x64</Platforms> solution wide to all of the *.csproj files with VS Configuration Manager.
