Outlook 2003 Addin fails to load for 32 bit Outlook 2010

Hi All:

The subject pretty much sums up my issue. I have an addin built that
work on Outlook 2003 and Outlook 2007, but when try to use in Outlook
2010 it does not even show up in the addin list.

If someone could shed some light or point me to a more appropriate
news group I would appreciate it.

Thanks in advance,

Kevin
