Upplay for Windows is built on Windows 7 and known to work on Windows 7, Windows 10, Windows server 2016 and 2019 (and maybe others?). It does not run on Windows XP.
The Upplay source code is free and licensed under the GPL. As a regular user, and in a nutshell, you are free to do what you want with the program (use, copy, share, etc.). If you intend to modify and redistribute Upplay, you need to take a better look.
However, I request a small fee for downloading the Windows binary version, it helps to motivate me to build and maintain it, as I don’t regularly use Windows.
The version of the current Windows download is 1.4.10.

This message will sometimes occur when starting Upplay for the first time after installation.
I need to fix the setup file, but, for now, you can download and install vc_redist.x86.exe from the following Microsoft support page
