Please ensure you have updated to Astute Manager v2 before proceeding. An easy way to tell the difference is that v2 operates in a larger window, whilst v1 was constrained to a smaller, vertical window locked to the top right of the screen.
As of the Astute Manager v2 it is no longer necessary to be concerned about activating or deactivating plugins. This is now an automatic process when logging in or out of the Astute Manager.
If you want to uninstall the plugins:
In the Astute Manager, click on the 3 dots next to the "All installed" or "Buy" button. You will see an option to "Uninstall all plugins".
After doing this, if you want to entirely uninstall all plugins and the Astute Manager from your system, please do the following:
Log out of and then uninstall the Astute manager
Manually delete Astute Graphics plugins from inside the Illustrator plugins folder.
On a mac, you can delete the plug-ins by going to the Applications Folder > Ai > Plug-ins >
On Windows, use the standard Add/Remove program system as described by Microsoft here.
