I've just installed the CS6 upgrade on my WIndows VIsta x64 bit machine.
Just now, I opened a folder of files in Bridge CS6.
I highlighted one of the files and selected Ctrl/o to host Camera Raw in Photoshop, which is what I always do.
But, I got an error message saying that Windows cannot find Photoshop CS4.
I did uninstall CS5 after installing the upgrade, if that makes any difference.
For some users an uninstall of previous version wrecks havoc with file associations.
First try edit/preferences/file type associations. Click on reset "reset to default associations". If that does not work click on individual file and set default to CS6.
If the above does not work you either have to unistall CS6, run the Adobe Script Cleaner or read registry solution in this link. http://forums.adobe.com/thread/1005273?tstart=0
I had this problem today. I unistalled CS5 after installing CS6 and it started asking for CS2!!!
I did the regedit quoted by Curt and it worked fine - no need to reinstall. You have to edit the registry then you can list CS6 in the file associations under Windows. I had to reboot to get it to refresh, but it worked OK.
I agree with you - we shouldn't have to do this.
