ArcEngine 10.1 needs Java to be installed and ArcEgine finds Java by '''registry keys ('''(not''' by environmental variables like JAVA_HOME and PATH).

<pre> Loading jawt.dll failed. This is normal if java.version < 1.3. If java.version is > 1.4 and if this failure has occurred on Windows,<br/>please ensure that this program is started with a Java executable from a JDK/JRE install location on this computer. <br/>at '''com.esri.arcgis.interop'''.NativeObjRef.getJdk13WindowsHandleNative(Native Method) </pre></li>
