XBMC won't launch

Hello, I have recently been using XBMC on my own computer but now I am trying to use it on another computer. I am getting an error with the sqlite3.dll file which I believe is something to do with the program not being in the correct directory. I can't place it in 'C:\Program Files' for a few weeks as I don't have full privilege to install it within there. I can place it anywhere else in my documents and the C drive though. So I guess my question is, is there a way to change the directory that XBMC uses to locate the files to run it?

Thanks.
