windbg.exe: Failed to load data access DLL, 0x80004005

I'm trying to debug a 32 bit process dump from a process that ran on an x64 machine. I'm running an x86 version of windbg on my x64 laptop. I've followed the recommendations here, but I'm still getting this:

0:000> .cordll -ve -u -l
CLR DLL status: No load attempts
0:000> !clrstack
CLRDLL: C:\Windows\Microsoft.NET\Framework\v4.0.30319\mscordacwks.dll:4.0.30319.17020 f:8
doesn't match desired version 4.0.30319.237 f:8
CLRDLL: Loaded DLL c:\symbols\public\mscordacwks_x86_x86_4.0.30319.237.dll\4DD234A8670000\mscordacwks_x86_x86_4.0.30319.237.dll

Verify that 1) you have a recent build of the debugger (6.2.14 or newer)
            2) the file mscordacwks.dll that matches your version of clr.dll is 
                in the version directory
            3) or, if you are debugging a dump file, verify that the file 
                mscordacwks_<arch>_<arch>_<version>.dll is on your symbol path.
            4) you are debugging on the same architecture as the dump file.
                For example, an IA64 dump file must be debugged on an IA64
                machine.

You can also run the debugger command .cordll to control the debugger's
load of mscordacwks.dll.  .cordll -ve -u -l will do a verbose reload.
If that succeeds, th开发者_运维技巧e SOS command should work on retry.

If you are debugging a minidump, you need to make sure that your executable
path is pointing to clr.dll as well.

As far as I can determine, mscordacwks_x86_x86_4.0.30319.237.dll is successfully loaded, but I still get the error. What am I missing?

I resolved the issue by using ProcDump to get 32bit dump of the 32bit process that was running on a 64bit machine. I can successfully examine that using 32bit windbg. There are more details in this blog post.

It looks like you have a 32-bit dump file - otherwise the error would look like

CLR DLL status: ERROR: Unable to load DLL mscordacwks_AMD64_x86_2.0.50727.3053.dll, Win32 error 0n87

At least that's according to the blog post “Failed to load data access DLL, 0x80004005” – OR – What is mscordacwks.dll? on the Notes from a dark corner blog.

Note the mix of AMD64_x86 vs the x86_x86 in your error message.

For me, it's always because I don't have the correct version of mscordacwks. It's also possible windbg can't find it. See my answer to Problem debugging hang-dump in windbg for one method I've used to find/extract the correct version from security patches. To get windbg to load it, I set set the image path for windbg to point to the directory I've stored it in.
