HandA&nbsp;this error&nbsp;0x80080203 usually indicates that the path passed to do staging from is incorrect or/and does not point to a valid appmanifest.xml.&nbsp;
&nbsp;
I usually troubleshoot this by mounting the VHD as and drive (E:) and manually browsing to the folder where the manifest is and comparing to what my code does.
&nbsp;

Stefan Georgiev&nbsp; Could you please give some more details of comparing manifest file with which code.

pjbalan&nbsp;not sure what we are talking about here...if you are looking into all the checks that are there in the MSIX format for MSIX app attach those are based on public APIs tied to APPX/MSIX.&nbsp;
