What error are you getting? Have you looked at the Fusion logs? You need to
provide more specific information and to do some detective work. For

I have developed an outlook Add-In using VSTO 2005 for Outlook 2003 which
should and by default also support Outlook 2007 which it is doing
correctly.
However when I am trying to install it on the machine with Windows 7
64-bit
and Outlook 2007. It some how giving a error and terminating the
installation.
I have developed this add-in on Windows XP 32-bit version using Visual
Studio 2005.
Any help or suggestion would be appreciated.
