# Windows installation with MS-Access database

The EPSG database is available in MS-Access format. Installing this database is the recommanded way to get the EPSG factory running. You don't need the MS-Access software; only the ODBC driver for MS-Access is required, and this driver is usually bundled with all Windows installation. Steps to follow:

- Download the MS-Access EPSG database from http://www.epsg.org and copy the `EPSG_v6.mdb` anywhere in yours file system. You can rename it at yours convenience.

- Open the ODBC data sources dialog box from the Windows's Control Panel.

- Click the Add... button and select Microsoft Access Driver (*.mdb).

- In the Data source field, enter `EPSG`.

- Click on the Select... button and select yours (potentially renamed) `EPSG_v6.mdb` file.

- Make sure that the JAR file from `plugin/epsg-access` (which contains only the `AccessDataSource` class and its `META-INF/services/` registration) is in yours classpath.
