You can get NIV Bible 6.0 software for Windows platform at ChristianBooks.com. Zondervan.com is another good source for NIV Bible study software or any Christian book needs.
To my knowledge, there is not a downloadable version. You can view it online from many sites such as BibleGateway. You can also download free bible software and if the NIV is not included, you will be able to purchase that translation and be able to read it. You can do this through the e-Sword Project.
