I'm a Vista x64 SP2 User. Before the SP2 released i installed Windows Automated Installation Kit (Windows AIK) 1.1 For: Windows Vista® Service Pack 1 (SP1) Windows Server® 2008 So, is this Windows AIK Version compatible with Vista x64 SP2 & ESET NOD32 Antivirus 4 (x64) ? By the way... I have Vista x64 SP2 & ESET NOD32 Antivirus 4.0.437 Home Users (x64) installed. But why i need the 32-bit Setup Version of NOD32 Antivirus 4, if i would build a Rescue-Disc ? Is that Rescue-Disc at all useful for Vista x64 SP2/ ESET NOD32 Antivirus 4.0.437 Home Users (x64) Users ?
