HI Gourav,
Thanks very much for taking time to reply and make a suggestion. I follow what you're saying but in my case Studio is not yet installed and also, as shown in my previous screenshot, the Studio install pgm is already using my local JRE (ie C:\Program Files\Java\jre7\bin\javaw.exe). Just need to figure out how to override the installation pgm's use of eclipse.ini so that the java parameter "-Xmx1024m" can be reduced.
