I have Acrobat Reader 9.3 installed. I installed Elements 8 Standard but can't run its tutorials that are in PDF format. I get a message saying" A sufficient version (8.1 or later) of Adobe Reader is detected but the version of Adobe Reader that is setup to handle PDF content is older than Reader 8.1".
My operating system is Windows 7.
I had Acrobat 5 on my computer. Thinking that this may be causing the problem I unistalled it using Control Panel. But this didn't solve the problem.
I welcome advice.
You probably ruined Reader by removing Acrobat after installing the former. I would start by removing all traces of Acrobat and Reader, and then install the desired version of Reader.
It worked! Many thanks for your excellent advice.
