参考命令：
.symfix c:\websymbols
.reload
loadby sos clr
~* e !clrstack

还是不行，完整的错误：
Failed to load data access DLL, 0x80004005
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 or on the symbol path
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 supported cross platform architecture as
the dump file. For example, an ARM dump file must be debugged
on an X86 or an ARM machine; an AMD64 dump file must be
debugged on an AMD64 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, the 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.
我试过网上所有的办法，都不行

我的Dump确实是32位的，而且加载的CLR版本也没问题，完全一样

我调试64位程序正常，调试32位程序就一直有这个问题，我换到32位的笔记本上面，也是同样的问题，是不是我这边的Windbg安装包有问题，你有链接么？

检查下 windbg 版本 和 dump 文件时的操作系统架构模式是否一致？
dump文件： x86
windbg: x64
