Hi, I am new user and I tried to install the add-ons from the help menu, but I see in the log that it says failed 
can some one help… I am copying the log info
~/Library/Scripts/Applications - Failed
~/Library/Scripts/DEVONthink Pro - Failed
For some reason there are ownership/permissions errors on your computer that have prevented installation of the add-ons.
See this forum thread http://www.devon-technologies.com/phpBB2/viewtopic.php?t=3790&highlight=ownership for a suggestion on how to correct that problem so that the add-ons can be installed.
