The latest version of Ez Keys a that is still available for downloading is compatible with Windows versions up to Windows XP. I just tried to run it in Windows 10 X64, but failed since it can't be tricked.
The only way to run the software in a Windows 10 environment is with the help of virtualization. Install Virtualbox and use an original Windows XP Install disc or ISO, then you can transfer the installation file and continue to use it in that environment.
