i had the same problem posted here-http://forum.avast.com/index.php?topic=82785.msg675810#msg675810-i could install everything but the firewall.my only solution was to pull the ethernet cord on the pc and put a linksys usb wireless in and use my wireless network,after i did that the whole ais suite including the firewall installed fine.after installed i took out the usb wireless and put the ethernet cord back in and it runs fine.i dont know maybe your situation is different but if nothin else works maybe give it a try.
this happened on win 7 32 bit-verizon fios
