I download the Gurobi package for linear programming. I import the corresponding gurobi.jar package. Then run the example program. Then it appears the following errors:

If you are still getting that error after installing the 64 bit JRE, it means that the JVM running Gurobi package is still using the 32 bit JRE.

Check that you have updated the PATH and JAVA_HOME globally and in the command shell that you are using. (Maybe you just need to exit and restart it.)

Check that your command shell runs the right version of Java by running "java -version" and checking that it says it is a 64bit JRE.

If you are launching the example via a wrapper script / batch file, make sure that the script is using the right JRE. Modify as required ...
