Light-build crashes after 34%

As soon as I go to build the light, the Swarm Agent starts up and gets to 34% and then crashes. I JUST installed U4 and it won’t let me build without crashing

Hi KeepSafeDistance -

Can you please upload a copy of your DXDIAG?

Thank You

Hi KeepSafeDistance -

This issue sounds like one that we have tracked down. It is a conflict in the drivers for the Intel Integrated Grpahics Drivers. Downloading the newest version of the drivers which can be found here:

will fix the crashing and allow you to continue to build lighting.

I should note that other users have reported that Intel (or their computer/laptop manufacturer) is telling them that they do not need an update. If this is the case, please check to make sure that your driver version is below the 15.36.21.64.4222 driver number. If it is at that driver number and you are still having this issue, please let us know. If not, one user had to force install the new update by downgrading his driver to an older version and then manually installing the driver linked above.

If this is not the fix for your issue please feel free to comment and reopen the question.

Thank You

Eric Ketchum
