when i double click my mxp file to load into extension manager i'm getting a "can't create folder" error message after accepting the terms.
i'm on a mac with lion 10.7.5, trying to load extension to adobe photoshop cs4.
actual error message says:
Can't create folder 'Macintosh HD:Applications:Adobe Photoshop CS4:Plug-ins:Panels'.
can't seem to find any other mac users with this problem and window user tips aren't particularly helpful.
i'd appreciate some advice.
