Not really techno-savvy, and just realized I have Acrobat Reader 5.0 -- apparently it's been updated a few times! However, it also looks like I can't just jump right into the newest 9.xx version. Can't tell if I need to start with 6.xx and work my way up, or maybe just trash the old version all together, and then download the latest and greatest? I have an iMac Power PC G3, OS 10.4.11, with sufficient RAM and HD space. Anything else you need to know?
Thanks for helping me figure this out!
You should uninstall v5 before installing a new version that is so far apart.
