I bought battlefield 2 but i didnt get a cd key

[GermanDarknes]

Because of this I kept the old solutions, they are still working of course.
It's nice to hear that it works, even with this little bug.

Hello GermanDarknes and world.
I tried the solution from DotDev (Second solutions outdated) because I refused to download an unknown software (I'm sorry :p).

First time, didn't work. Then, I removed the dash from the CD key in Regedit. Now, it works.
It's a long way but effective.

Now, some minors problems appear. All first connection after starting the game or disconnecting fail.
So, I have a restricted severs list.

Thank you for the solution. :)

[GermanDarknes]

Yes, so it worked for you, other users got trouble with their install script, for these user this guide is the correct way.

[GermanDarknes]

Changing CD-Key is not enough because Steam will always change it back.

oh ok I tried to rename it but it wouldnt let me but ill try again

@Juanny, it seems that you missed Step 4, than it should stay.

@skulz87, due a bug you have to do this with the steam version.

I updated the CD-Key Changer, it should auto-detect the operating system now.
