So, I haven't played PR for a while and tried installing again. At first, BF2 wouldn't start up after installing. I've gotten around that problem, but now there's another problem for which I'll need some help:

BF2 won't update to v1.5, even though I just installed 1.0 (or whatever, no updates yet whatsoever). I think the problem might be there because I updated my computer from W-Vista to W7 while BF2 (+PR) were installed and removed after that. I can't find any BF or PR files on my computer though, except for the ones I just installed.
Can anybody here help me out?
EDIT: Some raw info:
Operating system: W7 32-bit. Updated from Vista.
Processor: Intel Core2Duo CPU: P8600 @ 2.40 GHz RAM: 4.00 GB
It's a laptop.
