I am running elementary 0.2 (Ubuntu 12.04 but with a different desktop environment) and I installed Aptana studio. Everything is fine aprt from I can't get the internal web browser to work.
When I open the Aptana Studio start page I get the an error that says "we were unable to load the Chromium browser. Please check the documentation for details on possible workarounds/fixes. The message contains a link but you have to have an @aptana address to access it. Clicking on details after closing the error gives me the following which if very similar to How to set up internal browser for Aptana on Linux but I have tried MOZILLA_FIVE_HOME=/usr/lib/xulrunner and it did not work.
