Need help with downloading os

Hi all. Have tried to download the .428 os onto computer for installing purposes. Download appears to work correctly, however, upon installing I get a downgrading os option of 7.0.0.30 Nothing I do can get the 7.1.0.428 os to install. Obviously I cancelled the install as downgrading defeats the object. I'm currently running a 9860 on 7.1.0.402 The download came from this site and going on postings others appear ok so I'm a little confused. Have deleted the vendor file too.
Any help here would be appreciated.
Thanks

Hello Black a Berry, welcome to BBOS!

From your computer, you need to go to control panel... programs... and uninstall any other OS other than the one you want to install on your device. You should only have one OS installed on your computer at a time or when you go to update, it will automatically select the older OS.

Let us know how it goes!

Thanks for getting back. Should have mentioned I've already done that too.

You may have another vendor file that you need to delete. See here... http://www.blackberryos.com/blackber...-xml-file.html

If I may add to this, you might want to update your BlackBerry Desktop Manager software to version 7.0.0, released May 29, 2012.

Thank you.

Haven't done that. Thanks. Shall let you know how I get on.

Thanks for all the helpful messaging. Unfortunately I am still getting the older os come up. I have version 7 desktop, and just the 1 os on computer to download. This I have deleted and reinstalled. Both vendor also deleted and bin emptied. Must be something simple I'm doing wrong. Any ideas?

So when you look in control panel you see no BlackBerry OS versions listed there?
