Binary program packages for Linux, Windows, and macOS can be downloaded from http://www.ovito.org/.
Note that OVITO uses OpenGL to render particles and other graphical elements. Older computers or outdated OpenGL graphics drivers may not be compatible with OVITO. It is recommended to install the most recent version of your hardware vendor's graphics driver.
Extract the downloaded .tar.gz
archive using the tar command, e.g.: tar xzf ovito-2.8.0-x86_64.tar.gz.
This will create a new subdirectory containing the program package.
Change into the new directory and start OVITO by running the executable ./bin/ovito.
Run the installer program ovito-x.y.z-win64.exe
to install OVITO in a directory of your choice.
Windows might ask whether you really want to launch the program, because it was downloaded from the web and is not digitally signed.
Double-click the .dmg
disk image file to open it,
agree to the program license, and drag the Ovito
application bundle into your Applications
folder.
Then start OVITO by double-clicking the application bundle.
MacOS might refuse to start OVITO, because it was not downloaded from the official App Store.
In this case right-click the application and select from
the context menu (only required the first time you start OVITO).
You can also download the source code of OVITO and build the program yourself. See the developer section for instructions.
