Problem with WinFX Feb CTP, Sparkle and Cider

Windows Vista build 5308 is Feb CTP. That works with WinFX Feb CTP. Expression Interactive Designer (Sparkle)'s March CTP is compatible with those two.
Yes, you can also install Cider. Start here.

Sorry, Windows Vista 5342 and WinFX Feb CTP are not compatible. The Feb CTP of WinFX works well with Feb CTP of Windows Vista (I think that's build 5308).

Thank you Ashish.
So what's the solution
Where can I find a WinFX 5308 build Is that the only WinFX Which is compatible with Windows Vista
You mean there's nobody on earth who was successful running Expression Interactive Designer (Sparkle) on Windows Vista
Can I use Cider by installing the WinFX version published by Windows Vista
