Since Windows 10 is a new OS, I have not yet tested either Finale 2014 or the templates with this configuration. I would first suggest that you review the Read Me documentation and verify that all of the component files (XML, etc.) are in the correct locations. It's important to remember though that the documentation mentions only Win7 and 8.
There has also been some discussion on the Finale forums at MakeMusic running Win10 and Finale 2014. It may be helpful to check there as well for any relevant information regarding Win10 and Finale 2014.
