It's probably outdated. Last post before yours was from 2011. If you want to play custom maps, you can just join a server running them and they'll automatically download when they are played.
Installer for custom maps
- Thread starter Ducky
- Start date
Depends on the file type. It must be a .zip or .upk or .roe or simply a folder which contains the map files. I still use it.
Which is fatal - with Ducky's installer I was able to download custom maps fast and without problems. Now I waited for a long time to download some custom map (No Man's Hill or something like that) and when this was done I had to... download yet another map. It instantly turned me off from playing even though I had a long break from the game and wanted to play a bit today.
Apparently I was wrong about the installer being outdated, as Ducky states that he still uses it in the post above you. But I agree, it can be frustrating when you have to download a map via the redirect and you don't get it before the next map starts.
