NOTE: These databases have been upgraded to include the required data for Named Equipment Lists that were introduced in Version 9.2.4.

The Emfac databases must be stored in a specific location on your computer. To find that location, click on the 'Download Emfac Files' button under the 'Create a New Project' list in Step 1 of Urbemis. Next select the 'Proxy Serve Issues...' button. The message that is displayed will tell you the exact location where the Emfac databases should be stored.

If Urbemis is running, make sure you restart the program after downloading any databases.

Caution: Download ~ALL~ databases in a group. For example, for the Bay Area Air District you would download 10 files - the Bay Air Air District plus 9 county level files.
