Eclipse -vm option trouble

I'm having trouble setting up a new eclipse installation with the -vm option. I'm using the eclipse.ini file below (which has worked in the past). I need this for the m2eclipse plugin. Currently, if I include the -vm option eclipse fails to start.

Any idea what the problem is with this?

-startup

Are you using a 64bit version of Eclipse with a 32bit JVM?

I'm guessing its the space in the Program Files part of the path. The below example works fine for me. Can you try to install the JDK in c:/apps and see if the script below works for you?
