I've searched the web up and down but didn't find anything about the QianCai HandWriting System. I've also didn't find the software listed on any of the websites found which could also mean that QianCai HandWriting System is actually a discontinued application that doesn't have support for Windows 10. This could be the reason why you don't see the Chinese characters displayed.
Also, if you have the software in form of a zip package, make sure to install all the modules and all the supporting languages in Windows Localization (eg. Chinese).
