Security problem with Word 2007 add-in

[Eagle_Wizard]

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: Assembly ass = Assembly.LoadFile(this.FilePath); if (ass == null) return; //compilatie liep wellicht verkeerd System.Type T = ass.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?

Programming code is like magic, just use the right code (magic words) to make happen what you want..
