如何修复Eclipse Java虚拟机启动程序错误？

Question

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

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.
