If you’re trying to update Topaz Video AI within the app then, sometimes this doesn’t always work try using one of the links below which will do a fresh install for you
Having said that, if you already have this version installed then you are being reminded there is a new version of the Application Topaz Video the Studio version which is Subscription only.
I’m afraid there’s nothing you can do about that except ignore it, and continue using your current version unless you wish to upgrade to the new Subscription version.
As And-E said, sometimes the in-app installer does not update correctly. Try doing a clean install. If that does not work, please email the support staff directly at help@topazlabs.com so we can take a look and assist further.
