An older application I have includes a version of DAO 3.5 which it detects during installations needs to be installed on Windows Vista 64 Ultimate.
However, the setup for this DAO fails to install on Windows Vista 64.

I have read that there is a version of DAO which is included with Windows Vista 64, but it must be incompatible with this older application.
Is there any way to provide DAO compatibility within Windows Vista 64 ?
