Please stop saying we should "test" the installer, it obviously works.
As explained many times, each time there's an update, it might take a while for all nodes in the Cloudflare network to get the updated files and, since the installer is split in some pieces, if your local Cloudflare network still hasn't got the new files, it will result in a file corrupted message. It might take from a few minutes to several hours before all nodes get all the latest files.
Just try again later, and it will work.
