I have a document which was created by myself in word at home. A former employee allowed you to install Office 365 on my personal machine using the enterprise account.

I've since left that employer and built a new machine so can't access it anymore.

I need to update this document, it has things like textboxes which aren't enabled on the free version of 365.

I'm reluctant to purchase 365 to update a single document. Are there any free editors or wats of going this?
