Stuck at 87% while installing UE 4.8.1

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

Hi Aravil01,

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


Also, please be aware that the 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 the 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 the logs ASAP

I managed to fix the 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 the Engine and re-install does the trick…
