Downloads are now possible again.
I only just realized that there was a problem with them. It apparently occurred when I attached an SSL Certificate to my webpage for security reasons. The new address is https:// instead of http://.
Google Chrome announced that they will no longer allow downloads from unsecured pages. The problem lay, as far as I could tell, in my old internal links (some went back to 2014). These are closed now, replaced by new links to the bundles.
I have tested downloads on Chrome, Safari, and Edge, and all seem to be in working order, show secure, and confirm that my SSL Certificate is valid. If you have any difficulties downloading, please write me at email@example.com
