Hello Christopher,
Thank you for posting question on Microsoft Windows Forum.
Based on your query of installing MSIX files on Win11IoT. Well! Windows 11 IoT Enterprise (especially the LTSC version) is designed to be lightweight, which means it often lacks the Microsoft Store and the App Installer GUI. To install an MSIX file (like the new Windows App). You can try the following suggested steps by using PowerShell or DISM.
- Ensure you have the .msix or .msixbundle file on your local drive (e.g., C:\Downloads\WindowsApp.msix). Open PowerShell as Administrator: Right-click the Start button and select Terminal (Admin) or PowerShell (Admin). Run this PowerShell command Add-AppxPackage -Path "C:\Path\To\Your\App.msix" If the app has dependencies (like VCLibs), it might throw an error. In that case, proceed to the next step.
- In IoT environments, it is often better to "provision" the app. This ensures that the app is installed for all current and future users on the device. Open PowerShell as Administrator. Using DISM to add the package by running this command DISM /Online /Add-ProvisionedAppxPackage /PackagePath:"C:\Path\To\Your\App.msix" /SkipLicense Please note: Use /SkipLicense unless you have a specific XML license file provided with the app package.
