The official repository to download Tupi's installers is http://maefloresta.com/portal/downloads.php. Currently, there are installers available for Windows, Mac and Linux.
When the installation process starts, you will see a progress bar like this:
That's it. From now, you could find Tupi in your Applications folder and start creating your first 2D animation project! :)
Note: Currently, there are no official Ubuntu installers of Tupi's latest version. MaeFloresta provides a bundle installer easy to use but it is not a .deb package. If you use a Linux distro that is not Debian based, we recommend you to compile Tupi from the source code using one of our manuals.
Note: You can move Tupi's installation directory to any other path of your preference or to create a shortcut to the launcher from your desktop, to make easier to start Tupi.
