I'm trying to install KDE for Windows, from https://download.kde.org/stable/kdewin/ ... mirrorlist.

When I get to the "Download Server" selection step of the installer, I select the only option: World Wide (http://download.kde.org/Attic). The next screen, "Release Selection," is blank. Screenshot: https://imgur.com/tWzmbWx

Back on the Download Server screen, I've tried manually entering a bunch of different mirror URLs found lower on the kde4win page - for example http://kde.mirror.anlx.net/. Doing so does provide me some release choices on the next screen (screenshot: https://imgur.com/aoSawMq)...but then no matter which I select, the list of packages is always blank: https://imgur.com/6IRkFdp . I've tried a ton of mirrors, and a ton of release versions.

Searched high and low for a solution, but all I found was this other post (viewtopic.php?f=59&t=112029&p=269020&hilit=kdewin#p269020) from someone else with the same problem 6 years ago. But no solution.

Any help would be greatly appreciated.

Looking at the http://windows.kde.org/ page, looks like they've taken a federated approach where instead of installing everything through a single installer you download and install each (supported) application individually.
I think some of them may be available through the windows store as well.

...So then I guess the Kde for Win installer doesn't actually work anymore, and should probably be taken down & replaced by a note stating as much? Rather than leaving it available with no information so that users can spend significant time tinkering & trying to figure out why various URLs don't work...?
