Acrobat Pro X install error

I have to re-install my purchased Acrobat Pro X, purchased as a part of the CS6 suite. The other applications installed just fine. However, the Acrobat Pro X installation stops after 2% because it says "Please close these applications to continue" and lists SafariBookmarksS as the offending app. Thing is, I cannot find this "app" anywhere - it doesn't show up in Force Quit, and there was nothing found when I ran the Terminal killall command. I don't have Safari running and even if I did, there are no bookmarks! I tried restarting without effect. Is there any way to get around this?
