I am trying to install dropbox on my iMac at work, I already installed it on my two other computers without issue but on my iMac I get this error. Any idea how to solve this? 

The obvious suggestion would be to try repairing permissions on your hard drive with Disk Utility.
tags.
might give some clarification on which directory to change the permissions of.
open Terminal and type sudo open then type the whole directory written in blue then press enter. then paste the contents here in a new post with inCode:tags. might give some clarification on which directory to change the permissions of.[/QUOTE] I tried this and when I hit enter it just goes to the next line and does nothing. sudo open /var/folders/gZ/gZz+NuIDHZehAelkxnO2fE+++TM/-Tmp-/dropbox_errorovbEAU.txt :confused:
I did not reboot, I tried the go to folder and got folder not found. I can't figure out what would cause this.did you reboot? maybe it was removed. try copy and pasting the directory WITHOUT the txt file name into Finder's Go to Folder (command-shift-G) and seeing if the text file is there.
the reason i said try sudo open is because maybe the directory was inaccessible due to permissions, however now i think it can be accessed without root permissions.
