Illustrator CS3 can't print/save as PDF : Adobe illustrator

I installed CS3 and the error message:
"The Save as PDF and Save PDF as PostScript options in the Printer Dialog are not supported"
Does this mean that its not picking up on the Adobe Acrobat/Distiller 8?
How would I activate this? Help!!
Same thing with InDesign CS3, can't print/save as PDF.
(this is on a mac)

It may be looking for your RIP ppd, as well as Acrobat 8. Acrobat should have installed all the necessary files, but you might take a look into that. I don't think Distiller is part of the Save-As procedure. You might take a look into "Add-A-Printer" OSX option and select Acrobat 8 there ( although it should have loaded during the install ). Another option is re-install your printer's software and any RIP software ( if available ). Before you do, get whatever updates you can from the manufacturer. It could also mean, after you've done the previous suggestions, you correct permissions on your HD using Apple's Disk Utility. Leave the machine ON overnight so that the Apple Utilities can clean house while you're sleeping.

To activate it you have to launch Acrobat 8 and it will set it up for you on the first launch.

It will sk you if you want this to be so so do not dismiss it let it do what it hast to do.
