Hello,
I’m a new UE4 user and I don’t have experience.
I got the error below when trying to packaging for windows 64 bits:

I need your help.

I discovered that I had made a lot of mess in the project. I fixed the basic problems and built the package. The relevant item in the list was the need to upgrade Visual Studio. It was a beginner error but it has already been fixed. tks

@Podlasek, I’m having the very same issue. Could you please share what was the “basic problems” and how you fixed it. Thanks.
