COS Service fails to start

The COS Service fails to start. See screen shot for error and Diognostic report.

This came about after I was getting sync backup failiures with scyning to cDrive, error codes 9 and 55. To correct this I downloaded your fix to erics problem found at This caused login failiures. These login failiures I sorted by going through the forgotten password routine.

I have also tried running the repair option and uninstalling and re-installing.

Windows 7 64bit
Macrium Reflect free

Well, I got the COSService to work. Turns ouit it was CIS causing the problem.

On manually running a Sync backup to cDrive, the operation failed with:
01.12.2013 12:54:02 An error occurred during synchronization
01.12.2013 12:54:02 Saving final information…
01.12.2013 12:54:02 Synchronization complete!
01.12.2013 12:54:02 Synchronization process failed!
01.12.2013 12:54:03 Backup failed with code 55 (Access denied).

Debug info attached.

Copying files between Windows Explorer and through Instant Sync works fine.

Try to run the sync process as administrator.
The automated sync to cCloud is designed to run “as a service” so it has administrator privileges.


I have now uninstalled cDrive and installed cCloud. Ccloud works much better for the wayI prefer to work.

Thanking you for replying.
