The Microsoft Access 2007 runtime is now available at this link. Hooray!
You also need to download and install the Developer Extensions to allow you to build an Access 2007 solution that includes the Access runtime.
After installing these, I was a little nonplussed, as I couldn’t seem to find any of files to start the Packaging Wizard…which is the wizard to step you through the creation of a set of installation files for your Access application. This is now tucked under the “Developer” tab within Access 2007. There is no separate menu item off the Windows start menu.
