Hi Christoph, I tried with Sun JDK 1.7 by setting the JAVA_HOME to C:\Program Files\Java\jdk1.7.0_60.
I still get the same error: D:\OSGi\apache-karaf-2.3.2>bin\karaf.bat karaf.bat: Ignoring predefined value for KARAF_HOME Unable to update instance pid: Child instance started but no root registered in D:\OSGi\apache-karaf-2.3.2\instances\instance.properties Karaf can't startup, make sure the log file can be accessed and written by the user starting Karaf : D:\OSGi\apache-karaf-2.3.2\mvn:org.apache.felix\org.apache. felix.framework\4.2.1 Do you want me to specifically try with another java 6 version?
