Anton,

I to had this problem just today and could not find any good help on file associations. I am running XP Pro on Windows. I uninstalled CS2 and still had CS3 on the computer. All associations for InDesign, Illustrator and Photoshop went away. The only information I could find did not work.

This is what I did and it worked. I opened Control Panel, then File Options, and then the tab "File Types". I scrolled to the INDD extension and highlighted it. Then I chose the Advanced Tab, selected "new", typed in "Open" for the action and selected the InDesign.exe file. All Indd files associated with InDesign CS3.

I also repeated the same to get the AI and PSD files to associate.

I hope this is the right way to make the change, no guarantees, but so far it is working. Even CS and CS2 file versions show the CS3 logo and open correctly.
