Installing KStars

Before you install

Before you install, please note that currently, KStars may require quite some disk space, especially on Windows, as it requires KDE libraries to be installed. The installation process will automatically determine which KDE libraries need installation.

These libraries are shared by a host of wonderful applications, including Okular (an awesome PDF viewer), Amarok (a music player like none other), digikam (photo manager), to name a few, that you can also choose to install for very little additional disk space. See KDE Applications for more awesome, free, trusted apps that share these libraries.

Choose your OS

Choose your operating system for specific instructions. If your operating system doesn't provide binaries (executable programs), you may need to build KStars from source code.

Microsoft (R) Windows (TM)

  • Download the KDE for Windows Installer from here
  • Follow through the first few steps of the wizard. The wizard asks a lot of questions to provide flexibility, but for most people, the following answers should work:
    • Choose Install from the Internet.
    • Set your installation path (where you want to install KStars).
    • Choose End-User mode.
    • Choose MSVC compiler.
    • Choose a download path.
    • Setup a proxy server if required (sometimes needed if you are in a corporate or academic network).
    • Choose the mirror server nearest to you.
    • Choose the latest stable release.
  • When presented with the package selection screen, select "kstars" under "kdeedu" (Type 'kstars' in the 'Filter' box to find it faster).
  • The installer will automatically find which other libraries and KDE components are required by KStars in order to function, and show you a list. Just click next.
  • The installer will then download and install KStars and the other required components, and do some post processing and finish.
  • You should now find KStars in your start menu.

To uninstall, just delete the directory in which you downloaded the software. Since KDE / KStars does not use the Windows Registry, there is no formal procedure necessary to remove KDE / KStars. If you uninstalled KStars because you didn't like something about it, please let us know (either on our mailing list or on our IRC chatroom), so we can improve KStars and bring better free astronomy software to the world.


On most GNU/Linux distributions, KStars can be installed from your distribution's package manager (eg: Synaptic in Ubuntu). If you cannot find a package called 'KStars', you may need to install a 'kdeedu' package that contains all of the KDE Edu suite, which KStars is a part of. Again, uninstall is performed through your package manager. If you need help, you can ask on IRC (#kde or #kde-kstars on freenode. The #kde channel is more active and likely to be of immediate help.)


See this Wiki page for more details.

If you know specific instructions for installing KStars on Mac, please mail the webmasters / the kstars-devel mailing list (kstars-devel at kde dot org), and we'll update the site with your instructions.
