If you're deploying with the runtime, then the version of Access installed
on the target machine won't really matter, since your installation should
force your app to start using the runtime.

That said, there are numerous issues involved with deploying a runtime onto
a machine with a full version of Access. Before doing this, save yourself
some frustration, spend a few hours googling the newsgroups for subjects
like "ms access deploy runtime" and then add stuff like "retail version" ...

Select Access as the product, and enter "runtime installation", "runtime",
"runtime conflicts", etc etc
