    Security problem with Word 2007 Add-in

    In the add-in itself I use reflection.
    An other programmer can give me a DLL file with actions (functions) and with the class, namespace and the path of the DLL
    I can use these functions in my add-in.

    I tested everything in a windows application and it worked perfect.
    After that I tried to use the same code in my Word add-in but I got a Security error.
    Here is the code where I had the problem:

    Code:
    Assembly *** = Assembly.LoadFile(this.FilePath);
    if (*** == null) return;	//compilatie liep wellicht verkeerd
    System.Type T = ***.GetType(this.Namespace + "." + this.Class);
    
    object o = System.Activator.CreateInstance(T);
    T.InvokeMember(this.Method, System.Reflection.BindingFlags.InvokeMethod, null, o, new object[] { (object)dicArgs, (object)sConfig });
    The program gave a securityerror on the InvokeMember method.
    Probably I have to register the used dll somewhere in the .NET Framework 2.0.

    Can anybody help me fix this?
