Installation Instructions - Microsoft Windows

I haven't certified the application with Microsoft, so it will give a warning on first start-up.

  1. Double click the downloaded file.
  2. In the Windows warning box, click "More info".

   3. Click "Run Anyway"

Installation Instructions - Apple macOS

I haven't certified the application with Apple, so it will give you a warning on first start-up.

To avoid this warning, follow these steps to install:

  1. Double click the downloaded file.
  2. Click and drag the icon into the applications folder.

   3. Using Finder, navigate to your Applications folder.
   4. RIGHT click on the in Finder.
   5. Select "Open" in the list that appears.

   6. Click the "Open" button.

This process is only required the first time the application is started. After the first time, the application will start normally.

Installation Instructions - Linux

The application is packaged as an "AppImage" so it can be installed on most of the major distributions (Ubuntu, Mint, MXLinux, Debian, openSUSE, RHEL, CentOS, Fedora, etc.) On some distributions it will offer to install the software.

After downloading, you will need to change the file permissions of the downloaded file.

  1. Right click on the downloaded file.
  2. Select "Properties".
  3. Select "Permissions". (Example image from debian-based "MXLinux")

   4. Change permissions to executable. (Check "Allow this file to run as a program")
Known Issue: I have not been able to get the icons to package properly in the Linux AppImage, so the ugly default window icons are used now. I am working on a fix for this issue.


I have not integrated automatic updating functions into the application. To update you need to uninstall the old version, then download and install the new version.

Uninstallation Instructions

  • In Windows, click the "Start" button, then click "Settings", "Apps", "KADE", and select "uninstall"
  • In macOS, use Finder to go to the "applications" folder and delete the KADE application
  • In Linux, locate the AppImage file of the old version and delete it.
