Not a valid win32 application

[savvy]

Every version of Dolphin i get gives me the same error "Dolphin.exe is not a valid win32 application."
It is the x86 version im getting dolphin-master-4.0-411-x86 upto dolphin-master-4.0-422-x86.

Any ideas?

Windows XP is no longer supported.

Vista also has a similar issue: http://code.google.com/p/dolphin-emu/issues/detail?id=6805
Current builds are Win7 only until someone bothers to fix it.
