Hi.
ACCESS Databases can not be converted to executables, The ACCESS DB engine has to be installed in order to run the DB.
If you plan to distribute an ACCESS Database to users that do not have ACCESS you will need to purchase MS Office developer. MS Developer Edition has a runtime Version of ACCESS and once you buy the program it gives you the right to distribute this Royalty free run time version to an unlimited number of users, so they can run your databases even though they do not have ACCESS installed on their machines.
MS ACCESS Developer's edition is quite costly... Good deals can be found on EBay though.
