Unity 5 Crash Before Project Screen

I am getting a crash in Unity 5 before I even get to the project select screen. I have searched other threads and haven't found any one else with the same issue, and all the other solutions (anti virus, delete ProgramData/Unity, administrator mode, etc) don't work.

Here is the beginning of the crash log, can anyone help me?

Have you tried removing Unity 5, then re-installing?

 

Have similar problem I guess. I tried to install Unity on my new PC few hours ago. http://forum.unity3d.com/threads/unity-crash-at-startup.342876/



Ps. Where can I get log file ? I try to fing it in C:\Users\user\AppData\Local\Unity\Editor but its empty

 

If you go to your Console, then click the drop down arrow on the right. In unity.

 

Yes, I have tried reinstalling unity, I get the same result. Does the log file indicate anything useful? I can't read it, but it looks like the issue may be related to mono dev somehow? Thanks.

 

Do you mean Console window in Unity Editor? http://docs.unity3d.com/Manual/Console.html I can't open Unity. It crashed right after I try to open it. in the splash screen

 

UPDATE: I was able to download and run the 32-bit version of the software, no idea why the 64-bit version is refusing to run still.

 

Hmmm.. Have you tried disabling your antivirus software, then running unity as administrator? Also, try downloading a more stable version. 5.1.1f1 works good for me. Then make sure to add the patches.

Also, try holding down alt right after you click the unity logo. Does the project interface show up?

 

Tried all those things except the 5.1.1 version. None of them worked, and I never make it to the project interface. If there are no other workarounds I suppose I will work in the 32 bit version until a new update for the 64 bit version is available.

 

@ruj I did the same. It's works for now. Thanks.

 

Yeah, I hope unity resolves whatever is wrong with the 64 bit version, as it is one of the major selling points.
