The software doesn't appear to be available anymore. I have searched all the possible websites, but couldn't find any information about it. This could mean that it has been discontinued. However, if the IT guy said that it transferred all your application, then DLWin might be on your computer. Go to MY Computer > C > Program Files. The software might be there.
In case if it's not there, switch to desktop and press F3 to start the Search module. Type the name of the application and search through your computer.
