digi add-ins>serial console can't open in virtualbox

I install win7 in virutalbox, and also install vs2008 ,wince7 and digi jump start kit.
But I just find I can’t open serial console in digi add-ins menu.

it just nothing happen, no error prompt.
Any solution to help with it? It take a long time to deploy development tools. I think I didn’t miss any thing. just follow the welcome page and done what I have to do.

The only thing is I use a USB to serial port cable after the deployment, but I have drivers installed and it still not work. any method to check with it?

Hello, Is it windows 7 64 bit PC?
Which BSP version did you install?
The latest version Digi BSP 3.5.1 does not have this Add-in issue.
