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.
Unable to understand what might be the exact problem , still giving it a shot.

Appears to be the same issue , resetting JAVA_HOME and PATH solved the issue for him
