Error opening Eclipse-Collection of common programming errors

I am unable to open Eclipse IDE. The error displayed is as below

Any idea what could be the reason? And how do I solve this??

Note: I ran CCleaner recently (any registry issue??) and I got error executing my open Eclispe project. On restarting I get this issue. Is re-installation going to help? Am going to do that and update result here. And I would really like to know what caused this for future precautions.

Update: Same error for new installation. But this time got error regarding lauching JVM and missing dlls so going to reinstall Java.
