Windbg加载dump的时候报”Failed to load data access DLL, 0x80004005”错误
“Failed to load data access DLL, 0x80004005”这个问题可能有很多种原因，本文描述的一种情况就是客户的站点的.Net Framework的版本和本地调试机的版本不一致，以及解决方案。
废话少说，直接开工。(蓝色粗体命令为解决问题的命令)

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. |

# 提示信息比较明确，就是运行时环境的版本和调试机的版本不一致。于是我们从客户机上面把.Net Framework的目录拷贝过来。
#（当然，按照网上的说法，只要拷贝三个dll就可以了）
#拷完继续…
