Hi, Martin.
"Never will"? Maybe.
"64-bit WinXP or Vista will run all 32-bit software"? Maybe.
Did we both overstate our case somewhat? Maybe. ;^}
As I said, during the Vista beta period, I found several 32-bit programs that would not install and run in Vista x64. One that frustrated me was Adobe Photoshop Elements 4.0. But that one wouldn't install in Vista x86, either, at first. Another was Nero Burning ROM. By the end of the Vista beta, though, both those programs were available in versions that are now working in Vista x64.
I've never tried to run Dragon NaturallySpeaking, or any similar program. As of today, the Nuance website says, "Dragon NaturallySpeaking 9.5 does not support 64-bit versions of Windows Vista."

But that does not say "never will". Also, it does not clearly say that the 32-bit version of DNS will not run as a 32-bit application in WinXP x64, just as I'm now running Quicken 2007 Basic - a 32-bit program - in Vista Ultimate x64. That's what I meant to say in my quoted comment. Sometimes, "support" does not mean the same thing to users as it does to vendors. Many applications that are not "supported" will actually run, but we won't be entitled to get tech support from the developer if we hit a snag.
Have you actually tried to run 32-bit Dragon NaturallySpeaking in Vista x64, Martin? Or know anyone who has? What was the result?
