I just append -vm C:\\Program Files\\Java\\jre6\\bin\\javaw.exe
in ec
Recently I faced same issue.My version of eclipse didnt support java version 8.
I had accidently installed jre 8 on my machine which automatically updated my PATH variable by appending "C:\ProgramData\Oracle\Java\javapath" in the beginging which led eclipse to pick up this version(and ignore the manually added 1.6 version which came later in order)and crash with exit code 13.
I just removed this string from the path so which led system to pick up my older version and eclipse started just fine.
