ASP.NET + UCMA 4: Failed by SIPEPS v5

Hey there,

I would like to build an application with ASP.NET and UCMA 4.
With a console app, it works just fine.

After, when I want to start my ASP.NET & UCMA 4, I just cannot.
The debugger always yield at me:

"Could not load file or assembly 'SIPEPS, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."
With Google I found only spipeps v4.

Like in the console app, I tryed to change the target platform to x64. It doesn't work at all. It cannot start.

Is there a way to make UCMA 4 working with a Web App?

Thanks in advance.

Mafyou.

EDIT: I just done that with UCMA 3.5. I clearly need this with UCMA 4. Help
