I now remember what I did: I downloaded the Windows 10 SDK installer
(winsdksetup.exe) from:

    https://developer.microsoft.com/en-us/windows/downloads/windows-10-sdk

But instead of going ahead and installing the full SDK, which broke
something for me [1], I picked the installation option:

    (o) Download the Windows Software Development Kit .... for
installation on a separate computer

This will simply download all the separate installers that constitute
the SDK and put them in the specified download path.

Among them is:

    <DownloadPath>/Installers/Universal CRT Redistributable-x86_en-us.msi

And it is this specific installer I ran to get just the Universal CRT
DLLs installed, without having to install the full Windows 10 SDK.

I haven't been able to find this installer as a direct download from
Microsoft, only as part of the Windows 10 SDK.

Hope that helps. I'm attaching a screenshot showing all the stuff I
have installed on my Win 8.1 builder. Note that I'm using Microsoft
Visual C++ Build Tools (2015), to avoid having to install the full
IDE.

[1] I can't remember what broke right now, but I'm using the Win 8.1
SDK, so probably something interfered.
