error 1722 while installing symantec ver 10 on windows 2003 server

Symantec Antivirus Corporate Edition 10 was installed on a PC. Noticed virus definitions were not current and not coming in. Updated Liveupdate component, repair installed it, did not fix it.

Lastly did a complete reinstall. Install does not complete. Installer reaches a point and then starts rolling everything back.

The computer is installed by server 2003,What should be done to get it proper?

Thanks
