Number Machine Pro can be used on Windows computers ( XP, Vista, 7). We have had a few customers install this program on their Windows 8 machines but they needed to change settings to force their computer to behave as if it were an older operating system when using this program. You would need to consult Windows documentation to learn how to do this.
As always, we recommend you download and install the free Number Machine Pro demo prior to purchase to ensure that it will work as expected with your system.
This program is not compatible with any Mac (Apple or iOS) computers.
