The Digi Neo is supported under Windows Vista. Before we can tell if you are doing something wrong, can you provide the steps you are taking to install the card? Also, are you receiving any specific error messages during the installation process?

Only newer versions of the Windows driver support Vista. Which driver version are you trying to install?
You can get the latest version (8.0.20.0) here:
