I’m trying to open a project I made in Unity 5.0.3 with Unity 5.2.1, but after converting maybe 10% I get this error message saying “UnwrapCL.exe has stopped working”. Then Unity closes.

This is on a fresh installation of Windows 10 Pro.

So how do I fix this?

After a but if digging, I found another forum where the Unity guys gave an answer.
Here is the link for it.
http://forum.unity3d.com/threads/unity-5-2-1-crashes-on-fbx-checked-generate-lightmaps-uv.356859/

apparently they found the problem, but the updated patch to fix this updated patch won’t be released until the middle of next week it seems. So we have to wait a week to work on our respective games again…That’s assuming if the patch doesn’t break something else.

Same problem. Have been using UE4 for the last few months. Updated to the latest Unity and can’t even open projects.

I finally got it to load after making a new project, then from the File menu choosing “Open Project…”. Everything seems to work fine now.

Why this works, I don’t know…

So one potential solution is to delete the .meta files (if you have visible meta files) for the objects in question and resetting the ‘generate UV coordinates’ flag. You could try deleting the LIbrary folder if you don’t have meta files enabled.

I’m still getting this issue with the latest version of Unity. I downloaded it last night.

I am also getting this message and I only just started getting it today… not entirely sure why?

delete the library folder and meta
folder

  1. then open your unity project it will
    say " the asset need to be imported
    again" click yes!
  2. then it will import again and it
    will run !

Turn off Avira Antivirus. This is a 100% right solution.
