No, the software is not compatible with Windows 10. I've checked the official website and it appears that you can install RoboType on the following versions of Windows: Windows XP, Vista, 7, and Windows 8. It also supports both architectures (32 and 64bit).
If you want to buy the software anyway, make sure they offer refunds and then proceed with the buying operation.
