is COM registration possible ?

Occasional Visitor


I created an MSIX for my app which is a 32 bits Desktop application.

I have done it, the application install and launch correctly but I have one problem with a dependency.

My application uses a video filter to record MP4 files. This filter should be registered (rgsvr32) during the install but I don't know if it is really possible with MSIX... I think that we could only write in a "private" registry area.

Can someone explain me how to achieve that or why it is not possible ?

Thank you,

Hi @Frederic_Paillette,


In order to expose COM outside of your msix package, you must add metadata to your msix manifest.

See and related COM manifest elements.
