Why am I getting a 'Couldn't start Dropbox' permission error?
Here's the message that I get:
Couldn't start Dropbox. This is usually because of permission error. Storing your home folder on a network share can also cause an error.

This often happens with users who may have migrated old data and settings from another Mac to their current computer.
Operating system permissions prevent files from being viewed or edited by unauthorized logins. Permissions can be set any number of ways and can be restored manually through a fairly simple process. Please note that it is very important to follow these steps specifically as failure to do so may result in other issues. On a Mac OS X you can do the following:
1) Make sure the Dropbox desktop application is running
2) Click on the Dropbox icon in your menu bar and then click your profile picture or initials
3) Select 'Preferences'
4) Click on the 'Account' tab
5) Hold down the 'Option/Alt' key
6) Click on the 'Fix Permissions' button (make sure you're still holding down the 'Option' key.
This will allow Dropbox access to your home folder, Dropbox folder, and any required settings.

Hi I can't start dropbox on my laptop. I get this message
"Couldn't start Dropbox This is usually because of a permissions error. Storing your home folder on a network share can also cause an error."
I had a previous version running fine. so I uninstalled it and installed the latest version from dropbox website. Then it told me the folder dropbox already existed and it will be renamed and I clicked install. That's all I know. It has also referenced a log file and I have pasted the contents of this below.
Please help I just upgraded to a pro account earlier today

Ed - your solution is not useful for clients who "couldn't start Dropbox", as per the title of this thread.
I've encountered this error after changing the user folder shortname (and account names) of an OS X user. Now unable to launch Dropbox or reinstall as it repeatedly tries to follow a folder path that no longer exists.
I've cleaned all the preference files I could find, can you please let me know where to find the file that the Dropbox app is referencing for the bad folder path so I can simply remove it and reinstall.
