# Environment Variables

## Which Environment variables does IMSMA use?

There are three environment variables that are used by IMSMANG:

• IMSMA_HOME which normally should be set to c:\IMSMAng\
• JAVA_HOME which should be set to where Java 7 is installed e.g. C:\Program Files (x86)\Java\jre7
• AGSENGINEJAVA which should be set to where ArcEngine is installed e.g. C:\Program Files (x86)\ArcGIS\Engine10.1\
 Java 7 should be installed on the computer in addition to the Java folder in C:\IMSMAng. It is possible to have Java 8 installed too but JAVA_HOME and PATH must be to Java 7, see ArcEngine/Java issue for instructions.
