The problem is that you are trying to start a 64 bit version of Eclipse with a 32 bit version of Java. You can download it from here
Start Eclipse with a 64 bit JVM and the problem will go away.
To do so:
eclipse.exe -vm c:\path\to\64\bit\bin\javaw.exe
You can also update the the first two lines in your eclipse.ini
file to use the 64 bit java by default by doing the following:
-vm
c:\path\to\64\bit\bin\javaw.exe
Also, you can also download a 32 bit version of Eclipse for use with 32 bit Java. The key is that the bitness is the same.
