I have Adobe Reader 9. When i open a particular PDF document , it gives the error "Adobe reader could not open ABC.pdf because it is nether a supported file type or because the file has been damaged ( for example it was send as an email attachment and wasnt correctly decoded). I have attached the screenshot.
This particular pdf file has come as an email attachment ( using outlook 2003) . I cannot directly open from the mail client neither can i open it after saving it locally on my machine.
I am able to open other PDF email attahments and other PDF documents .
