It just says "this document requires the latest version of Acrobat. Go to http://get.adobe.com/reader to update."
I go to download it and I think it's version xl 11.0.08. I'm not sure how to open it directly in reader or how to find reader on my computer.
Yes I believe so. It's call pencast so the teacher will write and speak and it will turn into a PDF so that I can open it on my computer and hear what they are saying along with what they have written. I go to his website to access the pencast, it's not sent out via email.
