I have read another similar post where someone mentioned we need to associate .pdf with the PDF icon. but our problem is we only can't open this specific pdf file, others are fine.
If it is only one file you can't open then clearly the file must be corrupt. Have you tried opening the file directly from within the Reader by double clicking on it with your Windows Explorer?
yes, I download the file and open it with Adobe Reader, it works ok, no error, I just can't open it from sharepoint website
I am having the same problem but a little bit of a difference. I accepted the new updat to the Adobe X on 8/24/2011. Now when I scan a document I can open it on my computer but when I email it to anybody else on the netgwork the can not open it up on there computer. They can go into the share drive and click on it directly and it will open that way. But once again if I go to email it the document will not open. This problem needs to be solved fast as in my case this is being used for business purposes!!
