I think you will need to get some help rewording your question, because it is not clear enough.
Are you getting errors when installing the antivirus software ? what are the exact error messages ?
After installing the software, the message says “don’t send error” ? is it the windows message window that you see when a program has stopped working or has been killed from the task manager ?
What is the service pack level of the OS ?
What version of symantec antivirus are you trying to install ?
Are you installing it directly on the client machine, or from the antivirus server ?
The more details you provide, the better chances to get useful answers.
