Bump. We're having the same problem.

 

I wrote to Microsoft support and they said my online security package was causing the problem. This was relaxed and the file uploaded to MS Store packages but the following errors arose about the package:


The Manifest file looks something like

<?xml version="1.0" encoding="utf-8"?>

<StoreManifest xmlns=http://schemas.microsoft.com/appx/2015/StoreManifest>

<Dependencies>

<DirectXDependency Name="D3D11_HWFL_10_0" />

</Dependencies>

</StoreManifest>


In addition if one tries to create x64, Visual Studio certification check throws error as shown further below:



dump file attached.

So the only packages one can create are x86, ARM, and ARM64. These packages will pass the Windows App Certification Kit (but with warning below because deployment & launch tests cannot be done, i.e. one cannot check box below). When the app packages created are uploaded to Microsoft Dev Dashboard, they generate the errors shown at the start of this post above.

I tried doing all the above with a plain empty project from Unity Editor using all standard defaults and I cannot upload to the Microsoft Store. They are looking into it as well, but if you could reproduce the problem and advise that would help as well. many thanks.

The recent response from Microsoft is below, and it would be good if Unity to get together with them to sort out the issue, please. thanks

REPLY FROM MICROSOFT - UNITY PLEASE ASSIST

@EdwinOlima I am having the same exact issue. I fail the exact same tests. ( Cannot Launch App - even though the app runs fine on every device I have tested ).
Was the fix to disable Windows Defender? Or something in Unity?

For the xml issue I had the same issue too - fix was to just copy and paste the first line of this sample xml over the same file in Visual Studio - they don't even look different but somehow this fixes it and VS shows no squiggly line under the xml after I have done this.

 

Theo, thanks for the tip on the StoreManifest.xml file, it worked!

With regards the software that was blocking my upload, it was the "Online Security" setting that my internet provider has for my account. Using it, a web app, one can block access to gaming sites, social media sites from our home network. So what I had to do was, not to block these websites, and then I was able to upload the gameapp packages to Microsoft App store.

 

There's a UTF-8 non-breaking space (U+FEFF) as the first character. Can be deleted by opening the StoreManifest.xml file pressing Home to go the the very start and pressing Del to delete the invisible character.

 

Thanks @TickTockTech - I submitted a bug report. Hopefully it gets fixed.

 

@TickTockTech I also came across this weird issue when I attempted to upload my .appxupload packages; somewhat odd that it's an issue, to begin with. :/
