I'm running Adobe 8 Pro under XP Pro (fully up-to-date). I've started getting out-of-date messages on pdfs that I've downloaded. I've spent two days searching this question but to no avail: Can I run Reader X without uninstalling 8 Pro? I want to still be able to create docs but I'm not in a position to spring for the outrageous cost of the upgrade. Thankis.
The only supported combination is Reader X and Acrobat X.
Other combinations will only cause various, unpredictable results.
