I keep getting packaging error for windows 64. I have tried migrating levels into a new project and get the same problems. Help

Please, Post the full Log. Most problems will give you Unknown Cook Failure at the end. But the real cause of the error will be somewhere above it.

There’s a search box on the Output Log. Type Error in it and post the resulting lines here.

I am installing VS 2015 Community. Hopefully this solves the issue.

Here is the errors in the output log. Any ideas? Thank you.

Well, filtering by the keyword Error didn’t help. It must be an error that the compiler describes using other words. Can you post the full log in a text file? I believe AnswerHub won’t let you post that much text written here.

Please upload your output logs from the editor as a .txt file so I can help you further.

Thanks!

It seems I have found the culprit! A landscape at the bottom of a series of high rise towers. Once deleted it packaged fine. Thanks though

You’re welcome!
