No, you can't get a compatible copy that can be installed on Windows 10 because there isn't one. The Avanquest website lists the following operating systems as being compatible: Windows 98, Me, 2000, and Windows XP. This means the software won't run on Windows 10 due to compatibility issues, but you can apply a compatibility tweak: right click the setup package and then go to Properties > Compatibility. Choose another version of Windows from the drop-down menu and launch it. Additionally, tick the Run as Administrator option and then launch the software. It might work this way.
