you can download the access runtime instead of the full version and it will allow RR to run without requiring you purchase a license key for Access. The full version of access is not a free software and will continue to prompt for a license key so once you get the runtime installed, you'll probably want to uninstall the full version.
Try loading the 64bit Access Runtime here: https://www.microsoft.com/en-us/download/details.aspx?id=50040 I've seen this with 32bit access on 64 bit platforms.
Web Version now Available
First new Version in years coming soon.
