The latest version of Suunto Dive Manager is compatible only with Mac and Windows XP. There is nothing on the page to indicate compatibility with Windows 10. I've searched on the only website available, and I couldn't find anything about it. If you have an old version of Suunto Dive Manager, access the link below to download it.
In Windows 10, right-click the setup package and choose Run as Administrator: http://www.suunto.com/Support/Suunto-DM5/
