Version: (using KDE 4.4.0) Installed from: MS Windows If I lost my internet connection and the connection starts working again, the installer continues with the last download at same position and do not continues. Here where I am there are some connection problems, and sometimes I lost my connection and it's up again, but I can't exit home and let the installer working, because I lost my connection and when I back home at night the installer do not downloaded more than 1 or 2 additional files.
KDE 4.4 is outdated. If the problem persists in recent installer versions feel free to reopen this bug with an installer run log file, which is located in the download dir and is named kdewin-installer.log
