To do this, go to the "MySQL Server 4.x\data" subdirectory of the MySQL directory on your computer (e.g., C:\Program Files\MySQL\MySQL Server 4.1\data) and check to see if the "hapem_countyinfo_2000" directory exists. If so, the HAPEM Census Tract Database is installed. If you have not previously installed this database, download it from Section #4 (Input Data) above and follow the instructions for installing it.

Step 5. - Download "HAPEM (1 chem)" example application instructions. Print this file and follow the directions.

"HAPEM (>1 chem)" - This package provides instructions for setting up and running an example application where HAPEM calculates inhalation exposure estimates for multiple chemicals.

Step 1. - If TRIM has not been previously installed, install it using the TRIM Installer. Be sure to select "Inhalation Exposure Assessment with HAPEM" when prompted to "Please select the activities you expect to perform with TRIM."

Step 2. - Download HAPEM and accompanying input files from Section #3 (Software Available for Download) above.
