I tried to run \"eclipse-jee-juno-win32-x86_64\" , but it raised the following error \" java runtime environment JRE or java development kit must be availab
This worked with me: Eclipse will not open due to environment variables
Let eclipse use your java vm directly!
Put these lines at the end of eclipse.ini (located in the directory where eclipse.exe is present):
-vm
/bin/javaw.exe
Pay attention that there are two lines. Also make sure that the -vm option is before the -vmargs option (and of course after "openFile").
