Unknown System Error
« on: March 14, 2024, 03:08:50 pm »

Hello All,

In ACR -latest version- clicking on "Open Preferences Dialog" brings up the following: "Operation could not be completed. Unknown system error has occurred."

Not sure what to do.

This is all about finding a simple way to make an image in ACR look the same as it is in PS.

Any help appreciated.

Try resetting your ACR preferences, better?
Hold down the Command key and select Photoshop > Preferences > Camera Raw (MacOS*) or hold down the Ctrl key and select Edit > Preferences > Camera Raw (Windows).
Click Yes in the dialog that asks "Delete the Camera Raw Preferences?"

*On Ventura, it is now called "Settings".
