Stuck at 87% while installing UE 4.8.1

Good eveing,
I try to install Unreal Engine 4.8.1 and installation is stuck at 87% (launcher already downloaded all data)

Hi Aravil01,

Please take a look at our Troubleshooting Guide and follow instructions for including your dxdiag and Launcher logs, and include them in a reply here:



Also, please be aware that installation and verification process can often take a few minutes, especially on lower spec systems. It is common to appear to freeze for a while. Please let us know timeframe that you have been waiting.


I have been waiting for about 30 minutes but if needed I can keep it longer. Currently, I am experiencing some issues with my Windows and I need to restore my backup, so I will send logs ASAP

I managed to fix problem. It took longer than I expected but it installed. Thread can be closed

Hi, what did you do to make it work? same problem here thanks…

Ok, it seems in my case, than restarting Engine and re-install does trick…
