First, I had to first load a large installation file from the Internet during the installation on Vista 64-bit, as the corresponding installation files are not on the CD case and installing me a MSSQL Server and many other services were installed (was previously with XP Pro not so). The memory footprint was enormous. Alone the SQL services consume more than 200 MB. After my fresh patch Vista 64-bit computer was extremely slow and the pings escalated immeasurably. Impossible thus to work properly or play.
So my conclusion: "AWAY" in Vista 32 bit and 64 bit. And XP Professional 32-bit. Thumbs up!
