Norton Antivirus software installation failure

As I wanted to install Norton Antivirus software in my PC, a message like the attached picture appeared.
I have tried several times but failed. In addition, I am also having problems concerning ‘Active X’ during Windows Update.
I use Windows XP Home Edition and the second type of problems show some information related to my operating system.
I would highly appreciate any assistance which will help me solve it promptly.
