Hi,
Basically, you'll need to go delete the file that photoshop is seeing in your users "proofing" folder.
The file you need to delete SHOULD be here:
Users/[user name]/AppData/Roaming/Adobe/
Color/Proofing
If it's not, then here's how to find it in your version of Windows and Photoshop:
In Photoshop, go to: View / Proof setup / Custom from the menu
A dialog opens that you're used to where all the "proof setups" you've saved are shown in a list, below those provided by Adobe.
*These listed files are really "proof -setups" rather than "profiles", we try reserve the term "profile" for ICC profiles. Just to keep things simple.
Click on save there and you'll see the normal save dialog, at this point you may be able to see the route to the folder photoshop is saving to by default.
If that's not helping, I suggest you do this:
Save a new proof setup with an easy to remember name, say XXprooftestXX, allow the save to go ahead.
Next, in Windows, type that filename XXprooftestXX into the search window and you should now see the folder where your own proof setups reside, you can now delete the ones you no longer want to see listed in Photoshop.
IF Windows does NOT save your new setup to photoshop's default folder (it can happen) then simply search for one of your previously made setups by name using Windows search
I hope this helps
if so, please do mark my reply as "helpful" and if you're OK now, please mark it as "correct answer" so others who have similar issues can see the solution
thanks
