Hi All

Can anybody help me out with a problem ?

I have a word document that is password protected ? which means that when the document opens up it asks for a password ? So is there by any chance a way to detect if the document is password protected using OfficeToPDF v1.4

This is the error i get

__"Unable to cast COM object of type 'Microsoft.Office.Interop.Word.ApplicationClas
s' to interface type 'Microsoft.Office.Interop.Word._Application'. This operatio
