Zip Up Project: Uproject file says wrong version after unzip

Using File->Package->Zip Up Project I bundled up a tiny project so I could send it to my friend (we’re both using UE 4.9). However when the project is unzipped, the uproject file when double-clicked won’t launch claiming:

58754-couldnotcompile.jpg

Then I say Yes to rebuild which gives this error:

58755-tryrebuilding.jpg

Am I using this wrong? I assume when it says Zip Up Project it should be the whole self-contained project…?

Thanks for any help!

No one? Hellooo?

Is it a blueprint based project or does it contain C++ source code?

I had the same problem with my C++ project. Just happended because the “Zip Up” functionality forgot to add any source code or build meta information (icon etc.) to the zip. :-/
