Before this i already wrote a tutorial about free online apps that can convert office .docx documents to .doc file. That method is lame actually, you need to fill up an email and wait for the download link. Today i am going to tell you on how to open .docx files or documents using your old Microsoft Office version. This is really simple actually. All you need to do is just download and install the Microsoft compatibility pack
for your current version of Microsoft Office. It actually add the .docx support to your previous version of Mcrosoft Office. No need to buy Office 2007 .
