Thank you for your post. Based on the error you've mentioned, "Patch is not available for the language selected", we have seen this happen because we are not detecting the registry key is actively on your target machines. This means we are offering you a detection only patch which essentially means you're not able to deploy the patch. The below document goes over these types of situations.
Now, we have seen that even though your AV vendor is on the supported list, they are not adding the registry key like they should be. We have put together documentation that will be able to help you get this key deployed to your machines through our product even when your AV has not added the key as Microsoft stated they should.
Once you're able to get the key installed on all your machines, you can rescan the machines with your normal patch scan template and you should no longer see the same error.
