Error message: "Error 1316. A network error occurred while attempting to read from the file C:\WINDOWS\Installer\Symantec AntiVirus.msi"
The installer must first remove the previous installation and proceeds only after this has been completed successfully. If the installer cannot find the msi file to perform this action, the error occurs.

Navigate to or search for Symantec AntiVirus.msi.
