The VideoCam Suite application is developed by Panasonic. It's known until now, that Panasonic only provides updates to its applications. The latest version is 3.5 and it's not specified to work with Windows 10, therefore it can't be used.
There are other professional editing applications for your videos that you can use. For example, Adobe Premiere CC is the perfect solution since it can be used by beginners and advanced users alike.
