Hi, I recently installed Photoshop CS5, however every time I open the application, I am receiving this error message at the loading screen:
"Could not open a scratch file because the file is locked or you do not have the necessary access privileges. Use the ‘Get Info’ command in the Finder to unlock the file or change permissions on the file or enclosing folders."
I've looked online for solutions everywhere, but I've obviously been unsuccessful and I'm at the point where I have no idea what else to try, other than a clean install of my OS, however that is a last resort as I currently do not have an external hard drive to transfer my files to do so. So far I have tried these things:
- Reinstalled Photoshop many times, even the CS6 BETA is giving me the same error.
- Deleted preference files within /Library/Preferences/
- Used the cmd+alt shortcut when starting Photoshop to select a different scratch disk location.
- Used the cmd+alt+shift shortcut to delete the settings file, which I cannot do as the error message mentioned above appears before the window for deleting the settings file does.
- Tried rebooting several times, even into safemode and I still get the same message.
- Tried changing the permissions on the Applications folder, Adobe folder, CS5 folder and CS5 application, however they are all set to 'read & write access' for me. I am also set as an administrator.
- Cleaned my cache of any unneccessary files.
- I have also repaired my permissions using Disk Utility, but that didn't solve the problem.
I have a 2010 Macbook Pro, 4GB RAM running OS X Lion 10.7.3 with 2 patitions on my harddrive (OS X and Windows 7). I have 15GB free on my OS X partition currently, which may not seem like much, however I have run Photoshop CS5 previously as a trial and other versions of Photoshop and the small amount of harddrive space has never affected the software's ability to create a scratch file.
The strange thing, however, is that I can use Photoshop CS5 & CS6 on a guest account that I created recently, which means that the problem I am having is permissions based. Logging into a seperate account is a good enough solution for now, but it is incredibly tedious to keep changing accounts just to use Photoshop.
Has anyone got any other ideas? As I mentioned previously, reinstalling is a last resort as I currently don't have the neccessary resources.
