Where can we download symbols for Windows 8?

I am trying to debug a managed core dump, but it is hopeless, because the microsoft symbol server does not seem to contain the symbols for clr.dll version 4.6.1055.0.

Please, observe:

                       The system cannot find the file specified : srv*http://msdl.microsoft.com/download/symbols
                The SYMSRV client failed to find a file in the UNC store, or there
                is an invalid UNC store (an invalid path or the pingme.txt file is
                not present in the root directory), or the file is present in the
                symbol server exclusion list.

So, I went to https://developer.microsoft.com/en-us/windows/hardware/download-symbols in hope to download the right symbols. But how do I know which one to download? I did download and installed the ones for Windows 10, x86 32-bit retail symbols of Windows 10 - September 2016 and Windows 10 and Windows Server 2016 - August 2016

But none contained the clr.pdb matching the GUID 1C6AD585F62042AEB690C4C105CB9B962.

What should I do? I am sure there is a better way that downloading and installing all of them.

The web archive has a copy of the desired page from 2016-07-30 where the files seem to be available for download.

If version 4.6.1055.0 of .NET 4.6 was part of the OS at the time it was released, chances are that your clr.pdb is included. I still wonder why it's not available via the official symbol server, but it has happened before that Microsoft simply "forgot" to put it there.
