"Could not load file or assembly 'WebConnectionModule' or one of its dependencies'

I try to setup WebConnection 6 RC2 on a computer with 4.5 and 4.6 NET FrameWork and can't install
the 4.0 NET Framework

Thanks for your help

Make sure the Web Connection Application Pool is set to use the .NET framework 4.0 not 2.0.

The reason this happens I think is because you have an existing application pool that is used and the setting won't be changed automatically. A new install/project automatically would choose .NET 4.0 as that's the default with IIS 8 and later (and with the change I just added Web Connection explicitly updates the AppPool to use .NET 4.0).

THanks you, application Pool is now set to Framework 4.0 the error message change to

Impossible de charger le type ( Impossible to load the type .. )
'System.ServiceModel.Activation.HttpModule' à partir de l'assembly

PublicKeyToken=b77a5c561934e089'

Version Microsoft .NET Framework:4.0.30319; Version ASP.NET:4.6.1055.0

Hmmm... this is not something Web Conneciton loads. Are you mixing Web Connection with another project or other .NET code?

It's either that or you are pointing one of your extensions at the wrong module type.

Just to check you might want to try creating a new project and compare your web.config vs. the generated one. Specifically watch for the scriptmappigns and for any referenced .NET assemblies in the http runtime section.

Just setup on a brand new Win2012 server and everything was ok

The problem stay on the Win 7 computer with IIS 7.5, here is the complete error stack

I generated a new project and config file ar similar, here is the config section of booth I try with ISAPI setup and everything works fine except for the admin.aspx
