How can I open an Office 2013 document that is password protected without having to buy Office 365? My other computer is down, which has Office 2013, and I'm using my standby computer. I've installed Office 2007 Standard Home and my understanding is that from 2007 to present all docx documents can be opened by use of Office 2007 and following versions. The document has my passwords on it so if you suggest anything Microsoft or Office, which I have passwords for, I can't do it without opening this document.
