You should install both 32bit  amp  64bit java  At least JRE   that in case you re using 64bit OS

I think I found an easier way  for me anyway   Locate your javaw exe file  either by searching for it or just where you installed it   then drag the javaw exe file onto the eclipse exe file and it will use it

Eclipse and Java JDK  or JRE  must match regarding the BIT Version  For example   32 Bit Eclipse won t work with 64 Bit Java    32 Bit Eclipse needs 32 Bit Java

Here is the answer  sorry    but your solutions weren t correct   set PATH C  Program Files Java jre1 6 0 03 bin   PATH    paxdiablo  Did you rewrite the error or you got some kind of software reading text from image  if you got which one

Another alternative is to re-run the JRE setup   It typically installs a default JRE by placing java exe  javaw exe  etc  in your system folder   That would place the executables in your path  which should be sufficient  based on the note in the error message that it searched your path for javaw exe

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  lt your path to jdk jre gt  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     Useful link Eclispe ini at wiki eclipse org
