No
Every Windows Distribution is writen in binary non Open Source files. By the way, there are different versions of Windows Vista: Windows Vista 64-bit and Windows Vista 32-bit. Windows Vista 64-bit or x64 can work with 64-bit AMD Processors.
yes but a bit laggy and better on Windows 7
Maybe it's because of compatibility issues with 64 bit windows vista. If your not running 64 bit vista than it won't work on vista at all. Go back to XP. It might work on Windows 7, and it would definitely work on windows XP Mode. But you have to have pro or ultimate to have XP Mode. Since 7 is much better than Vista, you should consider upgrading. Otherwise, go back to XP.
Yes. Windows Vista fully supports quad-core processors.
I previously posted that Organizer does not run under Vista, but that answer was incomplete and misleading. It turns out that it does work on the 32-bit Vista platform, but not on the 64-bit Vista that I'm running. Sorry for the confuion.
As long as it's a 32 bit application, yes.
