If you receive an error that the document pack cannot install or that the base pack is missing, double check that a folder location has been chosen in Probate Plus for your document pack.
See : 'File...Options...Configure System...Files...File locations'. If the document pack path is blank, the document pack installer will fail. Solution : Provide a path for the document folder (eg a common folder on your network server so that all Probate Plus users can share the document library)
