I can’t open my unreal project. I get the message to rebuild it from source manually.
When I open the .SLN file in Visual Studio, I can build it with no errors. However, the project still won’t open in Unreal.
I can’t debug the project because when I attempt to, I’m told that UE4.exe is missing.
Perhaps try opening the epic launcher and verifying your engine install, maybe something got corrupted with it’s files.
UE4 (at least 4.27) does not have a UE4.exe file. These are the ue4 executable files in the Binaries\Win64 folder
Do you have the needed MSVC version and Windows SDK installed for the older of Unreal? This is usually the culprit if old project don’t compile nicely.
I tried the MSVC and SDK. I didn’t have MSVC installed but it didn’t help when I added it.
I don’t know exactly what happened, but the issue occurred when trying to switch branches in Git.
Fortunately, I’ve been able to reconstruct the project. Guess I won’t be messing with Git again without several backups lol
Check Epic’s documentation regarding visual studio setup. They list which version of sdk and msvc is needed for specific engine versions.
