When I try to install Kasperski active virus shield provided freee by AOL, I am unable to. Iget a message box which states ;- "WINDOWS INSTALLER This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package." I have had this program installed previously, but had to format drive ,and can`t instal now. I got this anti virus program from the Helpline pages many months ago and I find that it is brilliant nad would like to use it again. I have it on my new PC and would like it on this one. Has anyone any idea what happened?
