We are using LiveCycle only on Clients. And as far as I understood my Colleague this Error Message appears only when she wants to see a PDF preview of Document. In the LiveCycle Environment you have the possibility to do a PDF preview of a Document which you are actually working with. And this function does not work.
Hope you understood this Problem.
Could it be that this Runtime Error appears, because something is missing? Maybe .NET Framework 4.0 (actually we are using 3.5)
Thanks in advanced
