Installation failure

Hi, I posted earlier today - received error code 0xc007001c.  You suggested downloading the BFEFfix, which I did, then rebooted, and tried reinstalling, and I got the exact same error message.
the complete error says:  
Error code: 0xc0070643
and under additional message:  gives the avgmsi error27046  
driver installation failed 0xc007001c

Now, I am running on Vista, and I haven't been able to turn on Windows Firewall - which is why I am trying to install AVG,  just fyi if that helps in diagnosing the problem.  Thanks
