1.0.1 is shown as version in the manifest file and I dont know why it causes an error. And for Win10 SDK Version I used the number shown in the Visual Studio Installer for Win10 UWP SDK 10.0.15063.0. Any ideas?

I think it requires a four-digit version, e.g. 1.0.1.0.

When I open the manifest with doubleclick the version has 3 digits to edit. Worked fine in the past with some apps i uploaded to the Win store.

But I can try to open it in the editor and add .0 but it worked fine in c2 exports afaik. I Update the post later. Can't try it right now.
