Also, if this is an FTView SE project, you generally can't delete a project that has an alarm server defined, as the alarm server will start up as soon as your PC does.
Open the project, delete all the servers (including I/O servers), reboot your PC and try again.
If it won't let you delete the servers either, you may have to stop the relevant services in Windows first - note which ones you're stopping, set the all to manual startup, reboot your PC, open the project, delete the servers, close the project, restart your PC, delete the project using application manager, go back in and re-enable the services you disabled previously, and re-boot your PC again.
