Download them drivers using the link sent previously, once downloaded click on the download and new window will open, you will see the Drivers, right click on them and another window will open with a list Click on Extract Files to a specified folder, click on Local Disk c and you should see the Airnav Systems folder and to the right of it is a box with a plus sign, click on it and you will see Airnav Radarbox, click on it and you will see drivers, click on it until Drivers with a plus sign in a box beside it, click on the box and its contents opens then click on OK and the drivers will extract to the drivers folder
As Rod stated you should have installed the V6 software away from Program Files to c:\Airnav
You would be better using the Windows snipping tool to take screen shots as not everyone has Open Office installed to open ODT files
