Direct Unreal Plug-in installer can not find the Unreal® installation

 

Solution

The plug-in installer is looking for a specific Registry key and stops the installation with a warning message if it can not be found. Make sure this key exists by running the Windows Registry editor (“regedit.exe”). Look for:

Path:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\EpicGames\Unreal Engine\<VERSION>

Value:
InstalledDirectory – REG_SZ – <INSTALLATION PATH>\UE_<VERSION>

If this Registy key does not exist:

1. Download the following ZIP archive and extract the contained *.reg file:
   Direct Unreal Plug-in Registry File
2. Use a text editor (e.g. “notepad.exe”) and change the version numbers and the “InstalledDirectory” path in the *.reg file to correctly point to your installation. It should look similar to:
   

   Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\EpicGames\Unreal Engine\4.20] “InstalledDirectory”=”D:\\Program Files\\Epic Games\\UE_4.20”

3. Save your changes to the *.reg file.
4. Apply the changes to your Windows Registry by double-clicking the *.reg file.

Attention: Changes to the Windows Registry require administrator access and bear a potential risk to damage the Windows installation! Apply the suggested changes only if you fully understand what you are doing or consult your IT department for assistance.
