In that case, I don't know.
Installers are old versions, not updated? MS has updated some installers and they require sha2-code.
For example, I downloaded (from the old link) Visual Studio 2010/2012/2013/.… and could not install them in Windows -XP/Vista7sp1.
In Windows Vista and 7 sp1, they were installed only after the SHA-2Code update.
For Windows XP, it was necessary to find older installers.
