There isn't much information about the CROPWAT application, only a website, a download and some publications. I strongly suggest you access the built-in Help section to see what are the available features and in general how to work with it.
I've also extended the search query on other websites but didn't find anything about the issue raised by you in the question above. You can also visit the official website as well.
No, the application can't be used on Apple's OSX operating system because, according to the developer's information, it can run only on Windows platforms: 95, 98, ME, 2000, NT, and XP. On Mac you could try to run it using WineBottler. WineBottler allows you to run and install Windows apps without Windows OS. However, even if you manage to install it, the application won't have the possibility to communicate with MAC OS X version of Excel.
