Needless to say, Works 2004 is not supported on Windows 10, so there are no official solutions to your problem. You'll have to try this or try that and maybe something will work ... or maybe it won't.
You should be using a modern office suite. If you'd rather not pay $6.99 monthly to Microsoft to use Microsoft Office, there are plenty of modern, supported office suites that are free. Two examples (among many) come to mind: Google Docs, which is actually a free set of very competent office programs, and LibreOffice.
And both are also much safer than downloading old software from a third-party website. Who knows what you're really getting.
