In your config.ini file of eclipse eclipse\configuration\config.ini check this three things:

osgi.framework=file\:plugins\\org.eclipse.osgi_3.4.2.R34x_v20080826-1230.jar
osgi.bundles=reference\:file\:org.eclipse.equinox.simpleconfigurator_1.0.0.v20080604.jar@1\:start
org.eclipse.equinox.simpleconfigurator.configUrl=file\:org.eclipse.equinox.simpleconfigurator\\bundles.info

And check whether these jars are in place or not, the jar files depend upon your version of eclipse .

This can a time consuming problem. For those who want to get on with their work because they do not want to waste much time, I would like to suggest that you download the zip file and unpack the zip file and use it. The zip file is available for all major OS.

https://www.eclipse.org/downloads/packages/

Here instead of hitting the Download button, which will download the Eclipse installer, scroll to the middle area where a list of the various Eclipse IDEs with their respective features are shown. Select the Eclipse IDE of your like and click on the link on the right-hand-side to download the zip or corresponding file for your OS version.

If you still want to use your other Eclipse installations because, for example, you have plugins installed, then download the Eclipse installer and on the right-hand top corner press the icon with 3 minus. After that press Update, then after restart, install the version of Eclipse IDE, which you want (the one that you want to reactivate) in a different folder. The installation will take some time. After the installation is finished you should be able to start your old Eclipse IDE.
