Struggling with this problem right now. the unreal build tool .exe doesn’t exist in my installation at all. I have searched and searched for it, even in the Epic Games folder under Programs. I too have installed this not on the C drive, so that is why I am suffering from these problems. I cannot run any of the commands listed in these posts because the exe simply isn’t there for me to run them off of. I also tried to look at the clean.bat file, but it is very short and didn’t have a PBT path as described.
This all occurred after I tried to add an Actor Interface C++ class from within Unreal Engine while I had errors in my code. When it tried to do Live Reload coding, the build failed obviously. Then I began to notice changes to my cpp files not updating when I ran things in Unreal. I cleaned the project and the solution and it was all messed up from that point forward. Can’t even get into my project any more.
I can’t rebuild the solution files either, as it relies upon the exe, which I am missing.
My only resort at this point is to create a new project.
Edit: I found “D:\UnrealEngine\UE_5.3\Engine\Source\Programs\UnrealBuildTool\UnrealBuildTool.sln”, booted that up, built the project, and luckily it did make the exe that I was missing. I still can’t imagine why I wouldn’t have it to begin with because I just installed Unreal like a week ago. I ran one of the cmd commands from above posts, rebuilt the solution by right-clicking the project, rebuilt from within Visual Studio, and now am finally back to normal. Holy smokes this was a nightmare.
