If you don't have 3GB on your windies partition here is a work-a-round to install the latest patch -

Go to HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WINDOWS\CurrentVersion

Do not expand CurrentVersion node, just highlight it.
Find ProgramFilesDir variable in the window on the right side of the screen.
It will point to your program files directory (usually "C:\Program Files").
Change that path to folder on a drive that has enough space to patch BF2. Close regedit (this will save changes) and run the patch. After the patching is finished open regedit again and restore the previous value to the ProgramFilesDir (don't forget to do it - your system may become unstable if you won't).
