Error Out of Memory

[Powerpivoteer]

I am a user of Powerpivot.
I tried to load an xlsx file of 700k rows.
The powerpivot window gave me a message saying : no available resources smth - out of memory - Please try to upgrade to 64-bit if you are using 32-bit.

1) How can I learn what is my bit version that i use - where can I see it?
2) If I do use 32-bit > How can I upgrade it?

I use a laptop > Windows 7 >
Microsoft Office Suite 2010 Home & Student
> laptop is Intel Core i5 processor
> I have 4GB RAM

THANK YOU SO MUCH ALL

1) From your start menu, go to "control panel" and select "System". Here it will tell you whether you are using a 32 bit or 64 bit operating system.
2) I believe to upgrade to 64 bit, you would have to upgrade your windows OS to 64 bit.

Hope this helps.

Thank you susjoe3 _ that was an enlightening answer. I am out of home now so I will check later. I hope I am using 64-bit, if not trouble is ahead. Thank you again both you & the message Board of Mr Excel.
