If you are the John Doogan from New Zealand, then I went to one of your Photoshop seminars in Nelson some years ago. It was very good!
[EDIT] Sorry, I don't do Macs John, but I have never heard of the same version of Photoshop being installed twice to the same system (appart from the 32 and 64 bit separate installations). Can you go Help > About Photoshop in each instance to see if it is in fact the 32 and 64 bit versions? Although I have never manage to have those open at the same time.
Trevor, on PCs there's some kind of run-time check that Photoshop does that prevents two different copies from starting, even though they may both be installed. I don't believe they do that on Macs.
So the implication here is that somehow John has both 14.0 and 14.2 installed. THAT's a problem.
John, I can't unfortunately answer your question directly, except to add this comment: The way Photoshop CC is delivered, I'm sure you're not supposed to be able to get to the point where you have two different minor versions of it installed.
Restoring normal operation may be a matter of uninstalling all of them (Adobe offers a Creative Suite Cleaner Tool that will likely help with that), then getting just the one latest version installed again. You'll likely end up with a net gain in disk space.
I have tried un-installing photoshop. Started clean-up script but it didn't find anything on Photoshop CC to remove. Re-installed photoshop. Have been happily using Photoshop CC 14.2, double clicked a file in Bridge and another Photoshop starts up, version 14.0. I can't even find where this is located on my system. Frustrating.
I've tried unmounting a backup disc that might have the older version of Photoshop CC but still the old version fires up.
I'm not a Mac user, but isn't there some "task management" tool that will show you what's running, and what disk image it comes from?
John switch platforms. On a windows if I have any version of Photoshop and I try to open an other version I'm thrown into the currently open other version. Kind of wish I could do what Mac users can do open more then one version of Photoshop.
The task management tool is a good idea. It is called activity monitor on Mac and as yet I am unable to get it to show me which disk the application is being accessed from. Interestingly, I also have two versions of Adobe Acrobat pop open regularly 10.8.5 and 11.0.6.
You should be able to find the path by going to Help> System Info...
thanks steve, I think your suggetion nailed it.
I was getting the second instance coming from a backup startup disk.
And although I didn't get to take a class from John Doogan when I lived in Christchurch, he's a bit of a legend in New Zealand. I wish I had taken one from him before moving back to the States.
Did you get this sorted in the end? I seem to be having the same/similar problem. Photoshop CC is installed in my applications folder. My user applications folder is empty. Recently when I double click an image in Bridge it opens a second version of Photoshop that isn't the one that 'naturally' opens from the icon in the dock. I used Steve's suggestion to see the paths to these two versions - but there doesn't appear to BE two versions on my hard drive. If you have any advice would be appreciated. This has only happened recently I'm guessing with an update to PS CC.
Should my applications be installing in my user applications folder anyway?
I'm running El Capitan 10.11.3 on an early 2009 24" iMac 3.06 Ghz Intel Core 2 Duo.
If you've got time would appreciate any advice. Sam
I also started getting this problem.
I am on a similar computer running Yosemite 10.10
OK. Old problem apparently. I am now living in 2017. Adobe Photoshop CC 2018 is now out so if your reading this back in 2016......
This is what I have found. When opening a File to Edit in Lightroom Classic CC when having Photoshop open it will launch another "copy" of Photoshop.
Here's the trick. When going to the finder both copies show up as being in the same location, the application folder on the hard drive. This is not true, its a Apple glitch in my case. By going to my Bootable External Harddrive and opening my backed up Copy of Photoshop it wil jump to the one where I just opened my files from Lightroom. So now I know the location.
This is where Finder refreshes its info and shows the correct location of the Copy off Photoshop but the link to open the backed up Copy remains.In other words, Lightroom path is stil hooked to the backed up copy.
Since its CC and subscription based I just deleted the Copy from my External Bootable Back Up.
So I think the link is Created by Adobe, the file refresh path info problem is Apple.
Hope that works. Works for me.
