I'm running 64-bit Vista so I installed Eclipse for 64-bit Vista. The Silverlight plug-in works except for one big exception. The preview when editing xaml files uses 64-bit IE, and Silverlight is not supported in 64-bit IE. This is a showstopper because the preview cannot be turned off. Since you can't preview, you can't edit - it crashes.
I can’t figure out how to tell the preview to use the 32-bit IE engine. Is there a way to do this?
