What to do with “The version of SOS does not match the version of CLR you are debugging” in WinDbg?

by

This is what worked for me:

Download the following DLLs:

  • clr.dll
  • mscordacwks.dll
  • SOS.dll

from this folder on the machine that generated the dump:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319

Run the following command. The path to SOS.DLL should be without quotes, unescaped path delimiters:

.load path to downloaded SOS.DLL

I think a new WinDbg session is required for this to work.
