Added logic to support reading a 64 bit registry from 32 bit code.

Fixed logic to check to see if MSWord 2007 has the addin installed for PDF Export Added Unit RO support for MSWord Sections for U-Name, U-ID, U-Other Text, U-Other Number, U-Other Name, and U-OtherID Fixed code to handle Library Documents being remove from a list. Removed Debug Output
