After upgrading to 10.6 (Snow Leopard) Adobe Photoshop gives an error message on every start of the application:

"One or more files in the Adobe Application Support folder, necessary for running Photoshop, are missing. Please run the Phtoshop installer and re-install Photoshop."

How to fix this Photoshop CS3 on every launch error "One or more files in the Adobe Application Support folder" message that start occurring after upgrading to 10.6?

The problem is that /Library/ScriptingAdditions/Adobe Unit Types.osax isn’t loading. It’s possible the file is actually missing, but it’s more likely that you’ve upgraded to Snow Leopard.

Snow Leopard requires 64-bit versions of every plug-in, including OSAXes. The versions of Adobe Unit Types that shipped with CS3 and CS4 are 32-bit.

To fix this:

  1. Download the 64-bit version of Adobe Unit Types.
  2. Delete the old /Library/ScriptingAdditions/Adobe Unit Types file (when it's there).
  3. Drag the downloaded Adobe Unit Types.osax file to your /Library/ScriptingAdditions/ folder.
  4. Launch Photoshop.
