In rare situations the Direct Unreal Plug-in installer is unable to find the Unreal® installation even though a supported version is installed and works properly.
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:
InstalledDirectory – REG_SZ – <INSTALLATION PATH>\UE_<VERSION>
If this Registy key does not exist:
- Download the following ZIP archive and extract the contained *.reg file:
Direct Unreal Plug-in Registry File
- 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
“InstalledDirectory”=”D:\\Program Files\\Epic Games\\UE_4.20”
- Save your changes to the *.reg file.
- 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.
