Cannot Launch Photoshop CS5 - "Could not Open a Scratch File..."

paulieee Jul 2, 2010 9:04 AM

Hi, so photoshop CS5 is not launching.

Just got it in the mail, installed it, and now I'm getting this message:

"Could not open a scratch file because the file is locked or you do not have the necessary privileges.

Use the get info command in finder to unlock the file."

I've tried multiple things to try to resolve the issue including:

1) reinstalled 3 times

2) pulled all plists regarding adobe found at ~/library/preferences/

3) tried booting to safe mode, no difference

4) checked software updates for anything adobe, everything installed now.

5) note, this is also happening in photoshop cs2 now

6) tried changing permissions to enclosed items to the photoshop CS5 folder read/write access.

I've got a 21.5 iMac with Mac OS X 10.6.4 installed.

What other suggestions does anyone else have??

I have called adobe, talked to 3 different people, and talked to Applecare, each support rep

has told me to contact the other. I do not know what to do at this point.

Any suggestions would be greatly appreciated.

Sounds like a permissions issue.

Do you have the 12.0.1 patch installed? That should fix permissions issues.

yes, it's all up to date, I am totally stumped as to what file has the incorrect permissions...

I've got the same [edited by host] problem...
I've gone to the Windows Explorer Folders and the Files and DISABLED THE "READ ONLY" CHECK BOX ON EVERY LAST FILE & FOLDER REALTED TO IMAGES I'M ATTEMPTING TO EDIT...

BUT THEN IT RESETS THEM BACK TO BEING "READ ONLY" SEVERAL SECONDS LATER.

i'M THE ADMINISTRATOR ON THIS SYSTEM, NO QUESTION ABOUT IT...

I THINK IT'S ADOBE'S [edited by host] TOOLS....

ALSO THEIR HELP SECTION is poor [edited by host] TOO...

There is nothing in Adobe's products that could reset the permissions like that.

More likely you have a system problem, or are making simple mistakes.

Also, the scratch file is located in the system TEMP directory, not in the directory of the images you are editing.

I'm having the exact same issue on my Mac. I have 12.0.1 x64.

When I reset all the preferences using Command-Option-Shift during launch, I was able to open Photoshop. The area in Preferences for the Scratch disc showed my primary drive twice in the list. Maybe this has something to do with it?

I exited out of the program, but it gives me the same error the next time I try to open Photoshop. So it looks like it's refusing to save or read my Preferences.

It could be that the permissions have gotten screwed up somewhere, but what file am I looking for? I have run a repair permissions from Disk Utility, so that all looks good.

Never mind, a reboot of my system seems to have solved this. I think it may be that I accessed a disk image that I made of this drive, which is stored on an external drive, and so the system was confused about which Macintosh HD it was looking at.
