Where is the Visual Studio project file generator logfile?

Hi,

I have an older project on 4.13 and want to convert it to 4.18. My problem is that the VS project generation fails. The log window closes too fast to see the error and I can’t find a logfile.

I tried already to run it in a cmd

C:\Program Files (x86)\Epic Games\Launcher\Engine\Binaries\Win64\UnrealVersionSelector.exe /projectfiles "%~dp0\MyProject.uproject

But that only opens up the same fast closing window.

usually when there is an error it doesn’t close and stay open displaying the log how do you know it’s the vs file gen that cause a problem ?
