Unable to convert project to 4.11

I try to compile my project with UE 4.11, but I get the following error:

1>  Parsing headers for ProjectEditor
1>    Running UnrealHeaderTool "C:\Users\Arthur Masson\Documents\Project 4.11\Project.uproject" "C:\Users\Arthur Masson\Documents\Project 4.11\Intermediate\Build\Win64\ProjectEditor\DebugGame\UnrealHeaderTool.manifest" -LogCmds="loginit warning, logexit warning, logdatabase error" -Unattended -WarningsAsErrors -installed
1>LogModuleManager : warning : ModuleManager: Unable to load module 'ScriptGeneratorPlugin' because the file 'C:/Program Files (x86)/Epic Games/4.11/Engine/Binaries/Win64/' was not found.
1>LogCompile : error : Failed to initialize the engine (PreInit failed).
1>Error : Failed to generate code for ProjectEditor - error code: CrashOrAssert (3)

The project compiled properly under UE 4.10

Just some quick checks:

Are you sure 4.11 was installed correctly? Through the launcher?
Can you create a new project in 4.11?
Have you tried uninstalling and reinstalling it?

Yes, yes, yes, yes

Hm, if you’re able to create a new project, I’m not sure what it could be, unfortunately. The “file not found” part is especially bizarre.

You need to disable the exemple plugin: ScriptGeneratorPlugin in 4.10 then convert to 4.11. Or modify your .uprojet file in 4.11 to disable it. It worked for my project.

I am ashamed I didn’t see it earlier, I check my .uproject file a few times, but I had “ScriptPlugin” enabled; not “ScriptGeneratorPlugin” so I didn’t see my error…
