Wow Great Shawn I just want to ask a few questions again since I got a few application that is open by default such as .MP3, .JPG, .WMV, .3GP if there is something I missed (although I am rarely using it) do I have to add the extension ? and :D please review the bolded "Seven Forum" we are in Vista and I love it that way :DHello Duffster, and welcome to Vista Forums.
I added the PDF file extension to the list, but it will only set it back to the default of not be associated with any program since that is the default for PDF files in Vista.
Afterward using the download, try uninstalling and reinstalling Adobe Reader to see if it will automatically associate itself to open PDF files as it normally would.
Hope this helps,
