Depending on how you are geting the data formn the MDB, you may not need to have Access installed. Have you tried to run your tool on a PC that does not have Access installed?
If your tool requires Access, then the use must purchase Access or a developer can purchase the developer tools and the license to distribute the Access run-time version.
