If I try opening a photo in in camera raw in PS I get the message could not complete your request because the file format module cannot parse the file
this question as been asked before and the answer was basically corrupt files
It does not matter which files I have tried same result they are not all corrupt I have 100s
I have even tried downloaded stock photo's used with tutorials
ACR will only “edit” proprietary raw/open dng files - or rendered TIFF and JPEG. CR preference for JPEG/TIFF handling must be set to to one of the two active options, with the third option being disabled. Another option is to apply ACR as a “filter” from within Photoshop on rendered files.
