Out of memory (horizons mod pack)


I tried to load horizons on my computer and it says there isnt enough memory. I asked a friend and they said I needed a 64 bit computer and about 2g ram to run it, I checked today and my computer is a 64 bit and it has 3.75 bits of ram free and it still won't work if anyone can help that would be great thank you.


I found out I was using 32 bit java instead of 64 bit if you have the same problem go here -> http://www.java.com/en/download/manual.jsp and click 64 bit hope this helps I just didn't check java now it works!
