Is there a version or update to Lumen Micro that will operate correctly using Windows 10 64 bit?
It's impossible to say if the application is compatible with Windows 10 64bit or not because there is no place to acquire this information. I've checked all the websites and the results were zero. I've also traced the official website of the developers through Novel, but their products don't have anything regarding Lumen Micro which means it might be discontinued as well.
However, there is the possibility that Lumen Micro is available internally only, therefore a direct contact is needed: http://www.lumentouch.com/applications/web_cms/index.php?pageid=1494&menuid=1094
