Can't start Ecmt Manager

This is the general problem occurs in symbian generally when we Select the Preferences in the emulator. The reason could be either the java is not installed or new java version is not updated in the settings.
Solution:-

Check that the version information of the JRE exists in the config.properties file used by the ECMT framework.

Open the following file in a text editor:

\epoc32\tools\ecmt\config\config.properties

and add the correct version of the installed Java Runtime at the end of the epdt.java.version.start property.

For example, in a system with JRE version 6 installed, add ",6.0" at the end of the line:

epdt.java.version.start=1.4.1,1.4.2,1.5,5.0,1.6,6.0

Then restart the emulator.

This will open your preferences of the emulator.
