Support Office Cloud Provider integration when installed via MSIX

According to this Microsoft document to integrate with Office as a cloud provider you need to add a registry entry under HKEY_CURRENT_USER\Software\Microsoft\Office\Common\Cloud Storage.


This seems to not be possible at the moment for MSIX installed software.

Have you tried creating a modification package that contains this registry entry?


The files and registry contained by your modification package will be merged at run-time with the ones from the original MSIX package you have for office, so you should get the behaviors described in your request.


You can create it with the MSIX Packaging Tool or with other tools like Advanced Installer.

@Bogdan Mitrache Thanks for your suggestion. I wasn't able to test a modification package (yet).


Did I understand it correctly that I should create a modification package for the Office MSIX.


What I try to achiev is that my application (not office) that is installed via MSIX creates a registry key that Office (no MSIX) will read to display my application as a cloud provider.


If I understand the modification package correctly, it will add the registry keys to the context of my app, but not globally.

@Loki-Midgard I think I misunderstood your initial question.


From your first post I understood that office too was deployed as an MSIX package.


Modification packages will not work if office is not installed using an MSIX package. The modification packages are specially designed to extend/customize existing apps that have been deployed using an MSIX. In that case, the modification package would add the registry entries in the context of your app, not globally.


However, this is not your case.  A normal installation of Office will not "see" the registration from your application (installed via MSIX) because the registry entries from your MSIX are visible only to your application.


What you want cannot be accomplished with an MSIX. Apologies for the confusion.
