I am trying to create a setup for a standalone app with INNO

I've done this successfully in the past, but this time they fail on installation. The error message is about being unable to find the access point in msvcr71.
I am using Windows 7 (86) so there are two Program files/common/Microsoft shared paths. I am trying to install to an XP machine.

I've been noodling with this for a few days. Is there a INNO script to handle this situation. Ideas and suggestions welcome and gratefully received.
