Followed instructions and using all recommended versions for everything, anyone run into this ?

Are you using visual studio 2015 or 2017 ? In my experience, i had some similar issues when using VS 2017.. 2015 should work fine though

I tried both. First I tried 2015, then 2017. Maybe there's something wrong with my VS 2015.

We have seen this happen a few times when you have both 2017 and 2015 versions installed. I think if you try to force unreal to build with 2017 (by using the -2017 flag, this might help. Otherwise keep only one version should fix it

I've had issues regarding packaging Unreal.hx projects with VS 2017. Couldnt get it to work, installing and forcing VS 2015 and it packages as it should.. Couldnt really figure out what was the problem..

Thanks for the tip, will retry on a clean machine.
