PROBLEM with avast 6 internet security Installation

Hi to all…
Well… My problem is this:
After download the setup i click on it,run it as administrator…But when have to start the installation appear a window:
“An Error 0(00000000) has occurred.Last performed operation was:spawning”

Before doing this installation avast had some problems at the startup,so i disinstall it but i start the installation while the disinstallation attend the reboot…
Maybe is this the problem?What can i do?I MUST HAVE AVAST!
