How to fix Eclipse Java Virtual Machine Launcher Error?

So like the title says, Im having an issue with eclipse JVM launcher. Last night, everything was working fine, as far as I know, nothing at all has changed on my pc since then. However, I woke up this morning to find that when I run any of my projects in eclipse I recive this error: Java Virtual Machine Launcher- Error: could not open C:\Program Files\Java\jre1.8.0_60\lib\amd6jvm.cfg

I have already verified the integrity of my Path variable, (C:\Program Files\Java\jdk1.8.0_65\bin) Now at this point, you may notice, my jdk is on version 65. So is my JRE and java installation. I dont understand why eclipse is using jre 60. I also checked the preferences and changed the jre version too 65. No luck. Furthermore, I ran a simple java file without using eclipse through the command line and that ran/compiled just fine. I tried adding the -vm tag (It didn't already exist there) to eclipse.ini and setting it too the jvm but it didn't help. (I than removed it) I have no idea what to do... Please help, I've tried everything I know how to do. Thanks!

EDIT:

My eclipse.ini file below: 

-startup
../../../.p2/pool/plugins/org.eclipse.equinox.launcher_1.3.100.v20150511-1540.jar
--launcher.library
../../../.p2/pool/plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.300.v20150602-1417
-product
org.eclipse.epp.package.java.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash

256m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-install
C:/Users/Sanjiv/eclipse/java-mars/eclipse
-vmargs
-Dosgi.requiredJavaVersion=1.7

-Doomph.redirection.index.redirection=index:/->http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/

EDIT 2 I have already tried reinstalling java, eclipse and jdk.

For windows user, if your getting this error:

Java Virtual Machine Launcher- Error: could not open C:\Program Files\Java\jre1.8.0_60\lib\amd6jvm.cfg

it indicates there is no jre1.8.0_60 version in your system. So you need to set the JRE version which is already there in our system by executing the below command:

  1. Go to cmd prompt
  2. go to the eclipse folder (which you have installed) by executing: cd eclipse-folder-path

  3. execute below command: eclipse -vm jre_path
    ex:

    eclipse -vm "C:\Program Files\Java\jdk1.8.0_131\jre\bin\javaw"

Ok, so after a bit of digging, I managed to fix the problem. In eclipse, I went to Windows>Preferences>Java>Installed JREs>Execution Enviorments>JavaSE-1.8>Compatible JREs>jre1.8.0_65(perfect match). I have no idea why or how that changed, (or why it worked) but hey, I'm not complaining. For anyone else with the same issue, first do everything I said in the question body, then try this. It hopefully will work for you too.

EDIT: I just figured out the cause of the issue as well. I opened the workspace on another computer (my workspace is on a shared drive) running java 1.8.0_60 while this computer is running java 1.8.0_65. Obviously, eclipse had to change the version therefore causing problems.
