Cannot run Cocos Creator v1.10.2 or v1.9.3 setup on Windows

I’ve downloaded both the 1.10.2 and 1.9.3 Windows 7z files from the downloads page:
https://cocos2d-x.org/download

However, both give me ‘data error’ when using 7zip to unzip them.
They both extract a CocosCreator.exe file, but they are invalid executables and cannot run.

The 2.1.0 installer unzips and installs fine, but is of no use to me because I’m trying to see if I can use Cocos Creator as a GUI design tool for my Cocos2d-x project and the exporter does not work with Cocos Creator 2.0+ (See Integration of Cocos Creator v2.1.0 with cocos2d-x 3.17(c++))

Help!

Is there somewhere else I can find these versions, or can they be re-deployed to the download page so the archives successfully decompress?

Hello!

What version of Windows?

What version of 7-zip?

What is your locale?

Sure, I maintain an archive: https://digitalocean.cocos2d-x.org/

This was Windows 10 Pro 1803
7-zip version 16.04
Luckily I found a version from https://www.filehorse.com/download-cocos-creator/36006/ which downloaded and unzipped fine, and happily exported a c++ project created with this version (although it loaded a Cocos Creator project from 2.1, it failed to export)
