No, there is no updated version of Estate Planner to support Windows 10 on 32 or 64bit. I've searched on their website but all the links lead to a 404 page with no resources. Because of that I have to believe that Estate Planner is now a discontinued application. There is also no info about its return or if it will ever return.
I believe that you'll have to get back to the previous version of Windows (Start > Settings > Backup and Recovery > Get back) if you updated from Windows 7 or 8.
