Here’s a reminder of how to get the latest version of our InDesign plugin that is compatible from InDesign CC 2018 through to the latest version InDesign CC 2021.
We always host the latest plugin installers from this page on our help site.
The plugin has an auto-update feature, so when new versions become available, you will be notified that you can update from within InDesign.
If you happen to have a very old version of the plugin installed, you many need to uninstall it first. You can find instructions on how to do this here.
