Hello !
I’ve built my unreal editor from github source code (4.3.0 release), because I had some problems with launcher.
When I try to open project from editor the error is occurs: " Project flies could not be generated. Log output: Couldn’t find UnrealeBuildTool at ’ (…) Engine/Binaries/DotNET/UnrealBuildTool.exe’.

I’ve tried to open this project in Visual Studio 2013 and another errors occur: “One or more projects in the solution were not loaded correctly. Please see the Output Window for detals”
Message in Output window:
"C:\Users\Marta\Desktop\NANO T [Unreal repo]\nanot_ue4 4.3\Intermediate\ProjectFiles\NanoT.vcxproj : error : Project “C:\Users\Marta\Desktop\NANO T [Unreal repo]\nanot_ue4 4.3\Intermediate\ProjectFiles\NanoT.vcxproj could not be found.”

Please, can you help me? I’m really desperate right now.

Same problem.
In fact, when you verify the installation, the UnrealBuildTool.exe is there. Once you launch the conversion, the file is deleted.

Hi zgredziucha,

I just wanted to confirm that you are upgrading a game project from a previous version of the Editor to 4.3.0 built from source code? What was the previous version that you were using?

I was using 4.1.0 version of editor, than my launcher stopped working, so I upgrade editor from source code to version 4.3.0. The game project is already upgraded to 4.3.0 (It was done by one of my team members. It’s shared project)

I solve the problem.

Verify the installation
Check the UnrealBuildTool.exe is present in the folder
On your Antivirus, add the folder to avoid the antivirus considering the exe as a virus
Go to your project folder
Check if the intermediary directory has been deleted with the previous upgrade
If deleted, right click on the .uproject file and select the generation for visual studio project
Select also the engine version using right click
Now you can open the .uproject by clicking on it
Yes to recompile the source code
Everything should be fine. If errors during the compilation, open the Visual Studio project and fix

I hope this will help.
