Lookout won't start

[tinman141]

I have an Installation of Lookout 6.6 which stopped working.  It would hang at the splash screen.  After trying a re-install it again failed.  I have also tried uninstalling and installing Lookout 6.7.  It gives me the error "Fail to connect the Citadel service".  Processes  -  MSSQL$CITADEL is running.  Citadel5 will not start automatically or manually.  Any help would be appreciated.  Thanks.

Uninstall all NI products.

Uninstall SQL Server

Reinstall Lookout.

I have uninstalled and reinstalled Lookout and SQL Server more than once.  It has not remedied the issue.   

Re-install with Lookout 6.5/6.6 - Hangs on Startup (National Instruments Splash Screen)

Re-install with Lookout 6.7 - Hangs on Startup with error message "Fail to connect the Citadel service"
