Hi

I created a new profile for a user and copied the profile files belonging to another user profile to this new user, ensuring in the process that I set the correct permissions

Upon reboot Dropbox refuses to run : "Couldn't start Dropbox." permissions or network located folder

Here is an excerpt from the log file:

Traceback (most recent call last):
  File "dropbox\client\main.pyc", line 2443, in main_startup
  File "dropbox\client\main.pyc", line 1320, in run
  File "dropbox\client\main.pyc", line 553, in startup_low
  File "dropbox\client\multiaccount\instance_database.pyc", line 847, in __init__
  File "dropbox\client\mapreduce.pyc", line 54, in __init__
  File "dropbox\client\mapreduce.pyc", line 79, in new_user_key
  File "dropbox\keystore\keystore_win32.pyc", line 61, in store_versioned_key
  File "dropbox\keystore\keystore_win32.pyc", line 76, in _store_versioned_key
KeystoreRegKeyError: Failed to create keystore regkey!

I keep going round in circles trying to fix this
Uninstalled and reinstalled Dropbox several times
I tried login in as the previous user to clear the Dropbox registry entries

any ideas ?
thanks

Does Dropbox work in any profile?  

Uninstall Dropbox completely and remove all Dropbox files from ALL user profiles. Restart and install Dropbox. Does it now run in any profile?

If Dropbox works in the original profile, remove the other profiles (not "administrator), restart, uninstall Dropbox, restart again, and install Dropbox. See if it is working.

Now try a new Windows User profile and this time do not copy Dropbox settings. Set it up fresh.

In effect I had to remove Dropbox using the original user profile
but even this user couldn't remove the Dropbox registry entries.

I had to run regedit using psexec, from Sysinternals, then change
the owner of the entries in regedit before being able to delete them
