I also echo K4LSX as well on the yahoo group....Lets of helpful folks there as well... Go to Yaesu's site and find the FT-450 page, There will be 4 tabs- Description, Packages, Accessories and Files. Go to the files tab and download the PCC450 software. Once downloaded and unzipped, run PCC-450.exe. No install required, just the exe. Setup the com port and speed and you should have full rig control, including all menu functions just by clicking on the screen like you would on the radio. It should look like this..
