I just purchased 7250 at end of 2006. I was advised that for one specific application I needed 4.2+ Desktop & same on 7250. I found on website the Desktop Software v4.2 which I downloaded and installed but there seemed no way to upgrade device. I then downloaded Device Manager 4.2.msi and it proceeded to remove DM software.

I have experimented but where it should seem so simple - download software, connect device and upgrade accordingly evades me.

Thanks in advance for any help received
