I decided to open up Eclipse today and for some reason I got that error. Eclipse has worked until today, and "Programs and Features" does not show that any new programs have been installed. I have tried restarting and reinstalling Eclipse, the JRE, and the JDK, and nothing has worked. If there are any logs or other information that I should supply, please tell me.
The full path shown in the error message is:
C:\Users\oreo4\eclipse\java-neon\eclipse\plugins/org.eclipse.equinox.launcher_1.3.200.v20160318-1642.jar

It was more a question, did you install things into your Eclipse IDE.

What exactly is the name of the file in the plugins folder of the
installation? In my Neon installations it's exactly
org.eclipse.equinox.launcher_1.3.200.v20160318-1642 as you show below.
And this is the newest released version of this plugin...
In any case, the name of the launcher jar actually in the installation's
plugins folder must match exactly the -start argument.
When it worked they must have been the same. It should (could) only
change as a result of installing something in the IDE.

I don't understand what you mean by "Comments below".
EDIT: Never mind, realized you wrote in the middle of my post. The name of the file in the plugins folder was org.eclipse.equinox.launcher_1.3.201.v20160318-1642.jar, but now it is the normal one. Still getting the error.

That mean my comments inline mixed between your comments.

I've tried installing it again and figured out that it only works on the first run after installation.
