I've attempted installation of AVR studio 32 (for AVR32 UC3 development) and it doesn't appear to work.
Has anyone here gotten this to work in Vista 64?
Personally I use a virtual machine running XP...
I notice that Dean Camera (a regular over at AVRFreaks) has been playing with getting AVR tools to work on x64 boxes. See this posting on his blog: http://fourwalledcubicle.com/blog/archives/467. He also mentions that he's recently installed a beta of AVR Studio (http://www.atmel.no/beta_ware) which supports Windows 7 and x64.
