I have a customer running a BCM 50 3.0 who wants to purchase the LAN CTE keycode. They are running Windows Vista Ultimate SP! with Outlook 2007 SP2. According to the Nortel BCM50 LAN CTE Configuration Guide N0027154 01, Windows Vista operating system is not supported. However, you state above it works with a Vista 32-bit system.....is this correct? Any other issues if running on a 64 bit system?
