As far as I know—and I won't be shocked if I'm wrong—I have no AIR programs installed in any of my Macs, yet I see some AIR folders and icons on them. 
Is it safe to uninstall them? Is there an Unistaller somewhere, or can they just be moved to the Trash and nuked?
I do run Photoshop 13.0.5, Bridge 3.0, DNG Converter 6.4, Illustrator 12.0.1, Acrobat Professional 8.3.1, InDesign 4.0.5, Adobe Media PLayer 1.1, Adobe Reader and 9.3.0. Mac OS X 10.4.11 Tiger, G5 Quad PPC Power Mac.
Thanks in advance.
