Eclipse Installation Errors

I have been trying to install Eclipse on my Windows 10 Dell PC.
Here's how my eclipse.ini file looks like originally:-
-startup
plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.551.v20171108-1834

-XX:+UseStringDeduplication
--add-modules=ALL-SYSTEM
-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx1024m
--add-modules=ALL-SYSTEM
I have been trying to do the following:-
Changed version from 1.8 to 1.7 as I have installed Java 1.7
Added this before -vmargs
-vm
C:\Program Files\Java\jdk1.7.0_80\bin\javaw.exe
Also changing -Xmx1024m to -Xmx512m
But still some or the other error occurs and I am totally clueless about what is happening
I get errors like
Cannot create Java Virtual Machine
or
An error has occurred. See log \some\path in configuration folder whose content I am unable to understand
I don't have any workspace where I can delete .metadata/.plugins some file path to something call .snap where I can delete that
Also, tried -clean command, that doesn't works too.

I would start with cleaning your system, that means uninstall Java completely with all of its versions. Either that, or try to upload that log you cannot understand, maybe some of us will and it will shine a light on your situation.

Java crashes with Java was started but returned exit code=1

I use eclipse for android development.
Sometimes, if Google Chrome is running, it crashes and Eclipse also.
And I get message Java was started but returned exit code=1.
Full message is in print screen.
and my eclipse.ini :
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library

If your JDK version is 32bit then download Eclipse or STS of 32 bit.
If your JDK version is 64bit then download Eclipse or STS of 64 bit.This worked for me

Eclipse won't open after update from Ninite.com

I had Eclipse Juno installed on my Win 8 laptop. I then went to http://ninite.com/ and along with about 10 other applications, chose Eclipse and JDK. I ran the Ninite installer and after I came back my eclipse was closed. I've restarted my computer, but I cannot open my eclipse anymore. I don't know where Eclipse was located before, but searching my C drive, I see that an eclipse folder exists on the root of the C drive. I click it, and click eclipse.exe and nothing happens. Any ideas at all?

Grab a copy of Eclipse from the eclipse.org site and backup/delete the eclipse folder on your hard-drive. then extract the bundle you got from Eclipse.org in its place.

Try looking at the eclipse log-files.
