Hallo,
I bought from Element 5 my Internet Security 1 year license for Avast. I added the license to v5.0.396 Free Antivirus installed on Vista 64bit; Avast asked me to download some more files to allow extended features available in the Internet Security suite. After download nothing happend. Interface was still the same, no mention of Firewall menù ect…a reboot did not solve the problem.
So I decide to download the Avast IS package, uninstall the Avast Free Antivirus, install the IS version with the license and all went well 
Hope you can investigate a litlle about this possible bug.
Simon
P.S. Congrats for this new version. I’ve used the free 4.x for years. On my system Avast 5 IS is stable, no kind of mentioned BSOD.
