# Build error with UE4 integration

Hey I am trying to integrate the 4.5 UE4 integration into my 4.5.1 source build but I get a a build error: 1>d:\source_build\unrealengine-4.5\engine\source\runtime\akaudio\public\AkInclude.h(46): fatal error C1083: Cannot open include file: 'AkDefaultIOHookDeferred.h': No such file or directory

I put together the engine build then copied the integration into that folder with all the files from the audiokinetic that I needed to transfer. At this point I generate the VS 2013 files and try to build the project but it fails and gives me the error above. Has anyone experienced this problem?

You need to copy the Wwise SDK and the relevant files to UE4/Engine/Source/ThirdParty/Audiokinetic. Simply copy the following folders:

• Source: `c:\Program Files (x86)\Audiokinetic\Wwise v2014.1 build 5158\SDK\include\*.*`
• Destination: `UE4/Engine/Source/ThirdParty/Audiokinetic/include`
• Source: `c:\Program Files (x86)\Audiokinetic\Wwise v2014.1 build 5158\SDK\samples\SoundEngine\*.*`
• Destination: `UE4/Engine/Source/ThirdParty/Audiokinetic/samples/SoundEngine`
• Source: `c:\Program Files (x86)\Audiokinetic\Wwise v2014.1 build 5158\SDK\Win32_vc120\*.*`
• Destination: `UE4/Engine/Source/ThirdParty/Audiokinetic/Win32_vc120`
• Source: `c:\Program Files (x86)\Audiokinetic\Wwise v2014.1 build 5158\SDK\x64_vc120\*.*`
• Destination: `UE4/Engine/Source/ThirdParty/Audiokinetic/x64_vc120`

This is documented in Wwise_UE4_Integration.chm, at the "Installation" page. If you are having trouble reading this file, make sure the file is "unblocked" by right-cliking on it, selecting "Properties...", and clicking "Unblock".
