If you are using Symantec Endpoint Protection (SEP) and are having issues opening your EQ software, it is likely your Symantec Endpoint Protection software isn’t properly configured to run in unmanaged (standalone) mode. Symantec Endpoint Protection contains a feature called Application and Device Control that allows IT administrators to control how applications and devices can be used on the computer:

This feature can not be configured by the end user in unmanaged mode.

Again this issue only affects users of SEP running the software in unmanaged mode. If you are not running in unmanaged mode, please contact your IT Administrator to add permissions to your computer to run EQ Software. If you are running in unmanaged mode, please remove the Application and Device Control feature of SEP from your computer.
