Making dumps on Windows x64

March 1, 2012 at 4:35 PMalex

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

WARNING: MSVCR100_CLR0400 overlaps clr
The version of SOS does not match the version of CLR you are debugging.  Please
load the matching version of SOS for the version of CLR you are debugging.
CLR Version: 10.0.30319.1
SOS Version: 4.0.30319.235
