compiling the UE4PrereqSetup_x64.exe


so i want to change out some of the icons/images in the UE4PrereqSetup installer.
I found out, that under Engine\Source\Programs\PrereqInstaller\Resources you can find the used images. I switched them out for different ones, however, even after rebuilding the engine, if i package my project, the delivered UE4PrereqSetup_x64.exe still has the old images in it. Now my question is: How can i rebuild the installer so that it uses my images instead?


Open the PrereqInstaller.sln file in Engine\Source\Programs\PrereqInstaller and use that to rebuild the installer.

Hm yeah, getting some errors from signing when trying to build it.
““C:\Program Files (x86)\Windows Kits\8.1\bin\x86\SignTool.exe” sign /a /n “Epic Games” /t /v “obj\x64\Release\UE4PrereqSetup_x64.exe”” exited with Code 3 PrereqBootstrapper G:\UE4 Source\UnrealEngine-4.26.1-release\Engine\Source\Programs\PrereqInstaller\Sign.targets 25
