Microsoft Works Suite Doesn't Work Other Options?

my sister with "word" or "spreadsheet" stuff. We both had the Microsoft "Works" suite on our computers, so this was not an issue. She has Windows 7 and I had Windows XP pro, but now I have Windows 8.1. I soon found out that my old Microsoft "Works" spreadsheet would not "print" on my new Windows 8.1. It was suggested that I switch to the "LibreOffice" program. I did that. Took a while, but I converted all my previous "word" and "spreadsheets" to the "LibreOffice" program. I'm still learning how to use this program. But at least I can print those spreadsheets.

On a spreadsheet. If I send her a "LibreOffice" spreadsheet she will not be able to open it. There is absolutely, positively, not going to happen, that I can install "LibreOffice" on her computer and that she is going to learn how to use it. She uses her computer for basic stuff that she needs and that's it.

I need a program that I can install on "my" computer, that is "Windows 8.1 compatible and that then when I send her a "word or spreadsheet" she will be able to open and readily use.

Of course, if I could resolve the issue of why my "works" spreadsheet won't print on my Windows 8.1 that would solve everything. FYI, you get an error message that states: No default printer selected. Go to Control Panel and resolve.
