The patch is looking in the registry for the install (installDir) location. It should be in

HKEY_LOCAL_MACHINE\SOFTWARE\Electronic Arts\EA Games\Battlefield 2

If it is there you can modify it to the correct location, if it is not there, then you may aswell re-install as the odds are the cd key is also missing, which is usually in HKEY_LOCAL_MACHINE\SOFTWARE\Electronic Arts\EA Games\Battlefield 2\ergc
