The error you are seeing is a problem with the registry configuration which likely means the software didn't install correctly.
If it only happens on one environment, I'd say that it's a config issue. Please check to make sure that yoru version of InfoPath Form Services is the same and that all service packs have been installed. Try repairing the install or reinstalling.
