Reply to S4 with 32bit win7 and registration question

So, I've been rebuilding my laptop to use with the s4 that I got in yesterday. The problem is I can't find any drivers for my sony vaio vgn-fz190 for 64 bit versions of windows. The video drivers only work with 32 bit for some reason

Will this affect my performance?

Any other tips configuring this laptop will be appreciated. I followed most of the guide stickied in this community .

The other thing, if I install the s4 software and then have to reformat the laptop, the second time I install will count as the second install for the s4 software?

Thanks in advance
