Currently using have Vista Home on pc. Using Windows Mail for messagining. Why can't I open .pdf attachments to view them? The only option I have is to save locally, then I can open the file fine. Using Acrobat Reader 8. When I try to open to view file from Windows Mail I get the following: "This files does not have a progam associated with it for performing this action. Create an associatiom in thye Set Accociations control panel". I have checked the association settings and they are correct. .PDF files are the only attachments that I have this problem with.
