In some cases, a machine that is restricted by both Internet Security and 
Antivirus will prevent the NX Analytics from starting. To correct this, disable 
the NX Analytics. When NX does start, select FILE > UTILITIES > CUSTOMER 
DEFAULTS > GENERAL > MISCELLANEOUS and uncheck the following two options under 
"Product Excellence Program":

Uncheck "participate" 
Uncheck "Display initial startup message"

NX should start normally from now on.
