Never take a 64-bit dump of a WOW64 application. If you're on Windows x64, actually BY DEFAULT you'll be taking a 64-bit dump; so to take a correct 32-bit dump you have to manually start the 32-bit task manager (C:\Windows\SysWOW64\taskmgr.exe).

Otherwise half the functionality of WinDBG will not work, even with !wow64exts.sw. For example, you will be able to do !threads, but not !clrstack; !dumpheap -stat but not !gcroot.

Example error message (same as at http://stackoverflow.com/questions/6914291/how-do-i-debug-around-module-overlap-in-windbg-using-sos):
