PDFs saved from Safari won't open in Adobe Reader
iMac late 2009 8Gb 3.06 Intel Core 2 Duo - Safari 6
I encountered the same problem and tried doing what Suzanne did by right clicking the file and saving it to the computer first and then opening it.
And then after double clicking the saved file windows prompted whether I want to open it with the newly installed Adobe reader 9.0 or with Microsoft Word. I chose the Adobe Reader 9.0 and clicked on the check box asking whether we always want to open this type of file using this program.
I managed to open the file and best of all is after that I was able to directly double click on the pdf email attachments to open it.
Seems like that we need to let windows associate the file type with the program first.
