Unfortunately, this application is not available anymore. I've checked various websites found through Google Search, but none had any information about the CrossWorks application which means that it has been discontinued a very long time ago.
However, in Windows 10 you can install VirtualBox which will allow you to run Windows XP, therefore CrossWorks.
VirtualBox makes it easy to install and run older operating systems without affecting the functionality of your current OS.
Note: An original Windows XP installation disc is necessary to accomplish this.
