The CS version number and PS version number are inconsistent at least on the PC side of things and I think the Mac side uses the same version numbers:
CS5 has PS 12.x and uses ACR 6.x
CS3 has PS 10.x and uses ACR 4.x
Your message refers to CS5 PS 10.x.
If you mean you have PS CS5 12.x then one possibility is you have more than one Camera RAW plugin, somehow. Help / About Plug-ins... and note how many Camera RAW entries there are and what the version of each is.
I'm a Windows guy, but generally speaking since Camera Raw is a plug-in, you want to make sure you have only one Camera Raw.8bi file and that it's the one that's being loaded by Photoshop.
In Photoshop, do you see only one copy in the Help - About Plug-in list?
Search your Mac to see if you have an extra (old) copy of Camera Raw.8bi laying around that's being used instead of the one that's been updated.
This morning, I ran an update (patch) for Photoshop in the off-chance this would help my dilema (it didn't). I just now double checked. It's CS5 and 12.0.4.
Could you please double check to make sure Camera Raw is 'checked' in the updater preference?
Launch PSCS5 -> Help Update -> Click on "preference" make sure you have checkmark next to "Photoshop Camera Raw." Thanks.
There is only one copy of camera raw in the Help -> About Plugin (just checked).
I cannot find Camera Raw.8bi on my system. I tried Spotlight and locate (from the command line). I also tried searching for just 8bi. Same result.
Many thanks! That did it!!!
PS. That was a whole lot quicker and a whole lot more helpful than trying to get tech support through the phone with Adobe! I'm still grinding my teeth over that one!
…I cannot find Camera Raw.8bi on my system. I tried Spotlight and locate (from the command line). I also tried searching for just 8bi. Same result…
That's because there's no such file on a Mac.
".8bi" is an extension that denotes a Windows file, which would not belong in a Mac—ever.
On a Mac the correct Camera Raw plug-in is labeled "Camera Raw.plugin".
Tangentially, I recommend downloading and using the free Easy Find utility, which will find any file on your Mac, including many that are off-limits to the intrusive, useless Spotblight.
