I'm facing a problem right now and I don't really know how to get more informations about it.
I've converted a desktop application through Microsoft's Desktop App Converter, made some manual modifications about the visual assets, and rebundled it through "makeappx.exe". Then I signed it.
Everything went fine. Except that when I double click the appx to check it, I have the following window:
Which roughly translates as "Couldn't open the appx or appxbundle file" and "Reason: Failure caused by an unknown reason".
This does not helps me a lot :/
However, if I try to install the package through a simple "Add-appxpackage MyPackage.appx", it works perfectly fine.
Could anyone help me find some leads on what's happening here? I've already checked the event viewer as explained here but I couldn't find anything unusual.
Thanks,
Skefrep
It seems the Microsoft team has taken notice of this problem and investigated this appropriately.
