Apologies for the late reply. I need more information from you to investigate the OutOfMemoryError. Please provide below details -
1. Copy and paste your installation details. Open MyEclipse IDE, from menu options click on MyEclipse > Installation Summary > Installation Details
2. Clear your .log file located at [your workspace dir]/.metadata/.log, replicate issue and copy and paste relevant details here
3. Please include what are the steps taken by you which results in the OutOfMemoryError
If you would like to install ME without pulse, I would recommend you try our offline installers. Open http://myeclipseide.com/module-htmlpages-display-pid-4.html
, accept license agreement and click on the [download] link. This will redirect you to the next page with options to download. Click on [Download]. This will download the offline installer.
Let me know how this works for you.
