I am using Office 2007 Standard, with Windows Vista Business. Each
time
I attempt to open Outlook 2007, I receive a pop-up informing me that
InfoPath is not available, due to a missing file in Windows Installer (Error
1605). I cancel out of the pop-up, but Outlook opens in an unstable form
("not Responding"). After a couple of resets of Outlook, it finally opens
properly. I have searched all applicable Microsoft websites for help, but
can find no successful solution to the problem.

Any suggestions? I would be most appreciative of any help.
THANKS!!
