Installing Rule Designer

You add Rule Designer to an existing Eclipse environment.

Before you begin

You use Rule Designer to create decision services. To install Rule Designer, you must have the appropriate JDK and Eclipse for your operating environment already installed on your computer. Consult the download information in the cloud portal for more information.

Check the Java™ version of your Eclipse installation, and change it if necessary. In Eclipse, click Help > Installation Details. On the Configuration tab, check the version of Java in the java.version system property. You must use the SDK listed in the Rule Designer download dialogue box.

To change your Eclipse to the correct version of Java:

Close Eclipse.
Open eclipse/eclipse.ini, and add or edit the following two lines at the beginning of the file:
```
-vm
<SDK_InstallDir>/bin 
```
<SDK_IntallDir> is the location of the Java instance on your computer.
Restart Eclipse.

Make sure Eclipse and Java both use the same bit value, either 32 or 64.

Tip: If you get an error while installing Rule Designer, install the Eclipse Modeling Tools.
