Download
Windows 10/11 users can most conveniently install the app directly from the Microsoft Store.
Independently updated packages with broad hardware support are available in the Snap Store, on Flathub and via ppa:regal/dayon.
Otherwise you can download the latest installation packages for your platform from GitHub or SourceForge.
Windows:
Two installers are available and the installation should be straightforward. One package comes bundled with an OpenJDK 11 (LTS) based
JRE and one without. The one with included JRE is for 64bit versions of Windows only.
Since release 1.9 there also exist two separate "quick launch" versions. One for the assistant and one for the assisted part. These
two portable versions do not require to be installed. In order to avoid possible problems with user account control in these versions,
it is recommended to start the assisted with administrator rights.
Debian, Ubuntu and derivates:
So that you don't have to manually keep Dayon! up to date, installing it via ppa:regal/dayon
or as a snap is recommended.
PPA:
sudo add-apt-repository ppa:regal/dayon, sudo apt-get update and finally sudo apt-get install dayon.
Snap: sudo snap install dayon. Alternatively, you can install downloaded .deb
packages by tipping the command sudo dpkg -i dayon*.deb in a terminal.
Linux: either install the independently updated snap app via
Snap Store or via sudo snap install dayon
Alternatively, unpack the downloaded .tgz package via tar xzvf.
Run the script setup.sh, located in the target directory. The location of the installed
JRE/JDK is going to be detected automatically. It is not bundled in the tgz. If it should for whatever reason fail to do so, then you can
set the JAVA_HOME in (dayon.sh) manually.
Note that the .tgz packages have only been tested on various Debian and Ubuntu versions.
macOS/OS X:
Open the .dmg package and drag the Assisted or the Assistant onto the program icon.
If necessary, a suitable Java JRE 11 (or newer) must be installed.
Alternatively: unpack the .tgz package to a location of your choice. For more convenience you may
want to create an alias for dayon_assisted.sh and dayon_assistant.sh and copy them to your desktop. (Requirement: JRE 11 or newer also installed).
Important: From macOS Catalina and newer, you must explicitly grant screen capture permission:
