Can't install 5.7?

Development Getting Started & Setup

Dear Community,

For the first time, I cannot seem to install a new version of Unreal. When I click the “Install” button in the epic Launcher, nothing happens. I currently have 5.4.4 and 5.6.1 installed.

Any advice would be very much appreciated!

TIA,

Ben

Hello there @Ben_Blau!

Testing on my end, the install seems to be working as intended:

There could be an issue with your Epic Launcher, I would suggest a reinstall. And if the issue persists even after that, then the next step would be a full uninstall/reinstall of all Epic software from your setup:

  • First, uninstall the engine, launcher, any asset packs, etc
  • Next, open the registry directory HKEY_CURRENT_USER\Software\Epic Games\Unreal Engine\Builds, and delete any build entries
  • Finally, delete the folders %userprofile%\AppData\Local\UnrealEngine and %userprofile%\AppData\Local\UnrealHeaderTool
  • After that, no elements related to UE should be left in your system
  • Now, reinstall UE launcher from scratch, and only add the latest version of the engine (in this case, 5.7, you can add older versions after)
  • After the process is complete, test opening a blank project in 5.7
