Install the software - macOS
It is recommended you uninstall any previous version of TVPaint Animation you may already have on your computer before proceeding. To do so, simply drag the TVPaint icon from your Applications folder and drop it to your Trash.
Once TVPaint has been downloaded, unzip the ZIP file from your Downloads folder. Make sure to use the default macOS Archive Utility program to do this.
It is strongly recommended to keep this installation folder with all its files. It contains the software installer, the End User License Agreement and the After Effects import script file.
Double-click on the .pkg file contained in this folder to open the installation window and follow the instructions of the installation program:

Make sure that all of the installation components are selected. Then resume the installation:

You will be prompted to enter your session's password to proceed:

You may also be prompted with a message asking you if you want to allow the installer program to modify Apps on your Mac. Click on "Allow" to resume the installation:

The installation should then complete without any issues:

An application called CodeMeter will also be installed with TVPaint Animation automatically. CodeMeter manages your license and allows the software to run. It is necessary to install it in order to activate your license and for TVPaint to launch.
Do not download and install CodeMeter from another source as you could then be using an incorrect version of the application (which may prevent TVPaint Animation from working properly).
Once the installation is complete, proceed with activating your license.
The activation process will require you to use another web browser than Safari. We recommend using Firefox.
