The program's origin is unknown, therefore it's impossible to say if there is a version of Announcements for Windows 10. I have searched all the website, but couldn't find anything about it. Most likely, the program is not compatible with Windows 10, but if you have the setup package, right click it and go to Properties > Compatibility. Choose another Windows version from the list and then launch the installation. This is the only way when there is not enough information about the product.
