If you are seeing a "Host application with identifier ………... is not configured" error, the following steps should resolve the issue.
Uninstall and then reinstall Illustrator
• Quit the Astute Manager (Quit on macOS advice / Quit on Windows advice) >
• Quit all instances of Adobe Illustrator >
• Uninstall the affected version of Adobe Illustrator via the Creative Cloud >
• Reinstall the affected version of Illustrator >
• Run the newly installed Illustrator version to complete set up, then quit >
• Start the Astute Manager
Reset the Astute Manager
If reinstalling Illustrator didn't work for you, please try Resetting the Astute Manager.
Set default paths
If this doesn’t work, please go to the Settings section of your Astute Manager and click on the “Set default paths” button (example shown at the bottom of this page).
Further checks
If you are still experiencing issues, please check the following:
Do also check that you quit Adobe Illustrator before doing the update. If you didn't, quit it now and also quit the Astute Manager. Then re-open the Astute Manager and uninstall, then reinstall the plugins.
If the Astute Manager doesn't see your version of Illustrator after installing using the Creative Cloud, please see - Detecting and adding plugins to new installations of Illustrator.
Please also ensure that you do not have Illustrator installed on an external hard drive. Illustrator should never be installed on an external drive and doing so will cause problems.
Ensure that you do not have a beta or preview version of Illustrator installed on your machine, in this case the installer will try to place the plugin in that version's folder. To resolve this, open your Astute Manager and, in settings, check that the installer is pointing in the right direction, e.g. for Illustrator 2025 it should be: C:\Program Files\Adobe\Adobe Illustrator 2025\Plug-ins
Note that you can type the address or navigate to your drive (if necessary). This issue occurs due to the way Adobe internally names beta versions.Finally, if none of the above advice has resolved the issue, please contact us providing your account email address, details (or a screenshot of the error message), and details about your operating system and version of Illustrator.
