Microsoft Word version 2007 uses the docx format, to see them with an earlier version of Word, you only need to have an Internet connection and download an extension.
Currently, after forma tear my machine I have decided not to use pirated programs;), we will see how far my honesty goes; so I have opted to use Open Office. I have what I need for Word, Excel, Power Point and Access, but after searching through a multitude of pages that offered me an extension to see a docx file with Open Office I ended up arriving at a site that converts files online.
The site is http://www.docx2doc.com/, the guys who own this page are very clever, they make you convert 2007 word files to previous formats (.doc) and to earn money on the matter, they keep you locked for 24 hours, after this time you can download them.
Ah, if you want to download them immediately you pay $ 5.00 via Paypal or credit card and you are entitled to a full year.
My respect for your cunning, and in the hurry to send a document with urgency, instead of looking at sites that only sent me solutions for operating systems in Linux I had to leave the 5 dolaritos.
Surely there must be a way to do it with Open Office, an extension ... but I see that a good way to do business is to take advantage of the urgency ...
