Norton 360 wont open

i am not sure why i cant use REPLY button that i am sending as NEW MESSAGE.

 

my NORTON 360 cant open that i try to uninstall. Norton 360 Uninstall doesnt work because message advises "another installer is running. pls wait for it to complete." i have closed all programs that Task Manager shows blank meaning no program running. the uninstall problem still exists. i think this is the reason why Norton Removal Tool freezes and cant complete. pls help.
