Microsoft Office 2010

I come here humbly asking for some help. For some reason my microsoft office wont open. So I deleted it and installed the home and student trial, but it wont open still. I tried repairing it but it wont allow me to repair it either, any help?

Just use libre office. Or even Google Docs. Microsoft office should never be bought.

Forget MS Office.
Libre Office is just as good, if not better, and is free (freedom-respecting). Plus, it doesn't cost anything.
