with a download link for x64 here:
https://aka.ms/vs/16/release/VC_redist.x64.exe
Please try installing the library and see if it addresses your issue. I will update the documentation with the correct information in the windows.txt file in the next release.
If there is still a DLL import issue, make sure that Spyder is using the same environment that you installed the conda packages.
If this does not fix the dll import issue, a tool like "Dependencies" would help you find the missing dll:
Please let me know if this addresses the issue, so I can help further.
