Just use Bridge.  You could add the folder to Bridge as a favourite to make it more easy to access.

You probably have a32 and a 64 bit  CS6 in your computer.This is  fairly

normal. Are you running 32 or 64 bits? You may be trying to open in 32  bits,

but if your running 64 that MIGHT be the problem. If you open up MY 

Computer and go into Adobe, see if you have both.

                                    That's about the only thing I can tell

you other then calling Adobe and they  will give you free help.

I've been having this same problem, but no amount of Reseting File Associations seems to help. I've also tried associating the files with both the 32 and 64 bit versions of the applications. You can browse to it when trying to "Open With" in Windows 7, but when you click on it, it does not get added to the list.

I installed Photoshop CS6, then found CS5 was still there. I thought, hey, I don't need CS5 anymore, so I uninstalled CS5. then I found out that Photoshop was no longer available in 'Open with' when right-clicking an image...

So I went into the Registry, HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\open\command, and changed the (Default) from "C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Photoshop.exe" "%1" to "C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Photoshop.exe" "%1" (so changed CS5 to CS6) - and now I see 'Adobe Photoshop CS6' in my 'Open with' list when right-clicking an image...

Another big thank you to TinusHDCA.  I had exactly the same problem and doubt that I would ever have found this resolution without your guidance.  Your post is greatly appreciated - it simply sorted my problem.  If you have a few minutes please visit www.duncangrove.com .  It mainly shows a lot of overpaid celebrity tennis players thwacking balls at Wimbledon but there a a couple of other genres.  Not everyone's cup of tea though some seem to like them.  Inevitably there will be 2012 updates towards the end of this month! 

Thanks again - in all honestly I found obvious work-arounds o the isue but the need for this irritated me and I was determined to find a proper resolution.  People like you taking the trouble to share restores my faith in the internet community!

I didn't read the whole thread above, but did you try opening Bridge CS6, going into the Preferences - File Type Associations dialog, and clicking the [ Reset to Default Associations ] button?

For mine, the HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\edt\command was correctly set, however, the HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\open\command was set as

"C:\Program Files\Adobe\Adobe Photoshop CS5.1 (64 Bit)\Photoshop.exe" "%1". Surely there are some bugs in the installation program.

Thanks TinusHDCA.

yah, yah. I know, just to hightlight the edit part.

Thanks @TinusHDCA! Even my IT department was having trouble figuring this one out.

Just a note to others, this registry location/method above works for all the CS6 programs, except Fireworks. For Fireworks you must edit the value located at HKEY_CLASSES_ROOT\.png or
HKEY_CLASSES_ROOT\.pngfile

Also, Flash shows up as "FlashPlayer.exe" under the Registry, HKEY_CLASSES_ROOT\Applications but changing the value to "C:\Program Files (x86)\Adobe\Adobe Flash CS6 \Flash.exe" "%1" fixes the .fla file associations to Flash CS6 too.

From there you can further drill down to HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\open\command?

Yes, a thanks from me too.  I had uninstalled previous versions, and then found photoshop CS5. was not available in the lists of default programmes, which was true for most of the CS5.5 suite, although strangely, Illustrator was listed
