Package editor

To make changes to an existing MSIX package such as modifying the properties in the manifest or the content of the package without needing to package the installer again, you can use package editor in MSIX Packaging Tool.

From the welcome screen, select the Package editor icon, browse for your MSIX package and select Open package.

On the Package information page, you can change your package information through the fields in the UI or choose to open the MSIX manifest file manually in the editor of your choice to make changes to the manifest fields. While you are editing the manifest the package editor page is not editable. Once you save the manifest, the UI will get updated.

You can navigate to other sections of the package editor to modify your capablities, virtual registry, or package files. When you are finished editing your package, be sure to sign your package and update your version before saving your changes.


On the Capabilities page you can add or remove capabilities for the package. If a capability is present in the package, then the checkbox will be checked. If you select or un-select a capability, it will update your manifest. This translates to the element in the MSIX manifest.


The Virtual registry page shows all the packaged virtual registry entries for the application.
