I'm looking for the SOS.dll for .net 4.0.

I have 4.5 installed so my SOS.dll is not valid for the 4.0 builds we create.

Is there somewhere I can find the old version of this file?

You can find it in C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\sos.dll path.

For more info visit: Debugging Managed Code Using the Windows Debugger

I would recommend that WindDBG downloads the SOS for you, and for this visit Automatically Load the Right SOS for the Minidump

To get SOS automatically downloaded you need to have the Microsoft symbol servers set up in the _NT_SYMBOL_PATH environment variable.
Then run !analyze –vcommand which will grab the correct version of SOS from Microsoft.
The downloaded SOS will be put into your local symbol cache and loaded from there.
