Unsupported OS for x64 version

Question

I'm running Windows Vista 64 bit with Service Pack 2 which is listed as not supporting the Silverlight_x64 but is checked for the regular version. Will there be a version I will be able to use or am I missing that installation link somewhere?

Edit- I found that Silverlight 4 still works.

Answer 1

Unless you are specifically developing for 64 bit browsers (which most people do not run), you don't need the 64 bit plug-in. Just use the 32 bit one.
