Window Vista Problem

Using the OPTIONS menu of IE, select SECURITY. Scroll through and find the check boxes for downloading unsigned and expired ActiveX code. Remember what the current setting is, then uncheck the setting to temporarily allow expired or unsigned ActiveX programs to download.

Try your Veo Observer again, download the ActiveX and when you are sure it is working, go back to IE OPTIONS and change your ActiveX options back to their previous settings, which was to NOT allow expired or unsigned ActiveX code to download..
