I have the same problem… Seem that the hierarchy used in UE5 is different since it store the UnrealBuildTool.exe in its own UnrealBuildTool folder. I tried many things like moving everything in the subfolder in the DotNET and it gives a post execution error.

Also tried adding a path variable, checking the installation, just moving the .exe alone and using cmd and nothing seems to work.

UBT for the moment just works by doing it through the editor.

I will try some more stuffs but this is a big let down for the moment

For this problem i created a symbolic link that maps to the Engine folder.

My install location is C:\Program Files\Epic Games\UE_5.0EA

I created the sym link in *C:\Program Files\Epic Games* with mklink Engine UE_5.0EA\Engine

This is very meh, but i just wanted to open the editor xD

UnrealBuildTool.exe -projectfiles -project=“E:/unrealProjects/Mag/Mag.uproject” -game -rocket -progress

run from cmd work


To get the engine files in your solution you need to add -engine.

UnrealBuildTool.exe -projectfiles -project=“C:\UnrealProjects\ProjectFolder\ProjectName.uproject” -game -engine -rocket -progress


Same issue. All of the suggestions above didn’t solve the problem.

I also had to install dotnet 3.1.something runtimes to get it working via command line (even though I had no issues with missing runtimes for UE4)

Me too

Same issue here,
Now after installing Dotnet 5.0, 3.1, Visual Studio 2019 and using the command line I get this:

ERROR: Unhandled exception: System.Exception: Unable to find project file based on argument C:\Users\Schnittbrot\Documents\Unreal Projects\Pariser_Platz_5.0\PariserPatz.uproject

Same exact issue for me

Might have a solution. After going through the SLN file of a new UE5 code project (create a new code project from the launcher), I saw that there wasn’t really much to it, just seems to be references to a bunch of folders and such, so I compared it to my UE4 one, the only difference is the reference numbers (which I assume are engine specific) and a reference to the project name.
I copied the new one to my project, moved my old one to desktop and then renamed the new one to the original name, opened the SLN with word and changed the project name (hilighted green in the picture) and then saved/closed. Double clicked it and VS opened with the project right away.
Now I just have to go through my .Uproject and change the engine association in it from “EngineAssociation”: “4.26”,
“EngineAssociation”: “5.0EA”,
Set all 3rd party plugins to “false”
Here’s the raw code that you can paste into your SLN file, you just have to change the project name 2 times on line twelve (12) or eleven (11) Different text editors show an extra line up top. Change “ShadowWars” to your projects name.
Still unclear on how to get “UE5” to show in VS, but this is progress at least for me.
Edit: overwrite everything in your SLN file with this code, don’t leave anything from the original.

Don´t understand it , can you explain it a bit better how i get it fixed?

Use something like

“D:<your install folder>\Epic Games\UE_5.0EA\Engine\Binaries\DotNET\UnrealBuildTool\UnrealBuildTool.exe” -projectfiles -project=“D:\DNATG\UE5\ValleyoftheAncient\ValleyoftheAncient.uproject” -game -Engine -rocket -progress

should work

You need to start Windows Command Prompt

Then go to the drive UE5 is installed on, for me it was G
Typed g:

Then go to the directory where UnrealBuildTool.exe is located.
cd YourInstallFolder\Engine\Binaries\DotNET\UnrealBuildTool

Then run the UBT
UnrealBuildTool.exe -projectfiles -project=“C:\UnrealProjects\ProjectFolder\ProjectName.uproject” -game -engine -rocket -progress


“D:<your UE5 install directory>\Epic Games\UE_5.0EA\Engine\Binaries\DotNET\UnrealBuildTool\UnrealBuildTool.exe” -projectfiles -project=“D:<your project install directory>\ValleyoftheAncient\ValleyoftheAncient.uproject” -game -Engine -rocket -progress

Should work

I tried the command line approach using the UnrealBuildTool.exe located in the DotNET\UnrealBuildTool folder. It completed successfully but left me with several errors when trying to build in VS. (listed below)

EDIT: I made ton of files NOT read only and the project built successfully but still fails to load (gets stuck at 75% Exception thrown at 0x00007FFDA32055BA (UnrealEditor-RHI.dll) in UnrealEditor.exe: 0xC0000005: Access violation reading location 0x0000000000000110.)

I have not been successfully been able to build in VS neither yet. It has to do with the package managers (NuGet)

Worked for me thanks!
