I have the Manager set to check for updates only and not to download. However, turning off the Auto checking doesn't solve the problem. The Manager still isn't reading that the latest update is installed. Or, the latest update has in incorrect, internal version string.
This is the first time I've seen this behaviour from a Stardock update. I agree with Tarkus01, this is sloppy and it's been reported early enough that it should be fixed by now.
