Error in the "dev-vr-hololens2" branch of the Unreal Engine GitHub

I have been trying to set up the new “dev-vr-hololens2” branch for UE4 and I am close to the last step, but when building the branch I get this error.(see picture below)
Anyone have a solution?

Thanks

I will report on the bug. But this branch just got announced so I was hoping I maybe did something wrong or misunderstood something?

Yes, this is correct way to create interop.

For the signing, you should create new certificate in Project properties.

Thanks for answer, good to know it’s correct.

About the certificate, I have tried it many times, mostly blank as it says it can be in the docs. I click generate new and even when I try with or without password it says. CN=NoPublisher in the text field.

And I get the error “Signing key not found” error when building.

Have you tried this yourself?

Publisher of certificate and publisher in app must the same. The details about creating certificate with publisher is here

Looked. You should open Project/Description/Company Distinguished Name and assign the name in format CN=TheCompany. Then open Project/Hololens and click Generate new

That was it, it works. Thanks alot!

Okey so I noticed in the solution in Visual Studios that the file was actually missing, but I find it in windows explorer.

So what I did was to navigate too:
…\Engine\Source\ThirdParty\WindowsMixedRealityInterop
And open the sln file.

In a readme file it stated to build for all the following: MixedRealtityInterop x64 debug and release, MixedRealityInteropHoloLens x64 and arm64 debug and release.

This actually made it work, when I now build the UE4 it completed. The only question is if this was the correct way to do it?

Since when I now try to make an appx bundle in the editor it gives me a new error:
“Signing key not found. The app could not be digitally signed, because the signing key is not configured.”
