On a Windows 7 pc I copied a profile from one user over to another.
Upon loging in as the new user I obtained an error because Dropbox couldn't start.
The error log stated that Dropbox couldn't access the registry
I actually had to log on as the previous user in order to remove the Dropbox registry entries; neither the new user, nor the administrator account were allowed to delete the registry entries.
There is apparently a permission issue
Any ideas ?
