Yes, the client is working just fine on Windows 10. I've installed the full version of Diet Odin and everything worked normally without errors or special configuration. If you're planning to install it on the system partition, then a user with administrator rights is necessary to run it properly top save the data that you add into the application.
The version that I've tested was downloaded from the Alankit website: https://www.alankit.com/financialservices/odin-diet
