Re: Battlefield 1942 - Invalid Serial Key

This solution works, thanks for writing it up.

Thanks for the confirmation, glad I could help :-)

Thx, saved my day ;-)

Do you have any screen captures of your regedit screen?

BTW, I put my original CD-Key that I own.

And it still give me the "Invalid CD Key"

I may have to install my original game just to be able to play.

I don't think EA/Origin thought this one thru when they released it.

Did they even test it before the re-release?

When I saw this, I was excited, knowing that I might actually be able to finally play the game. However, something always goes wrong for me.

Going through the steps, I noticed i already had an Origin folder in the location for 32bit OS, so I went straight away to finding the product key. So, I right clicked Battlefield 1942 in Origin, but looking through the options, there wasn't anywhere for me to choose Game information/detail. The only options available were: Collapse, New, Find..., Delete, Rename, Export, Permissions..., and Copy Key Name. Any ideas on what's wrong and what to do?

No, you're mixing up the instructions. If I have some time today I'll make scrrenshots and post them.

it WORKS FINE!!!!! JUST FOLLOW YOUR STEPS!!! THANX!! THANX!!! THANX!!! VERRY MUCH!!!!

Please do it bro cause i got a little confused ,too .thanks in advance 🙂

This worked for me too!

Nice one, thanks 🙂

Hi all,

I've merged your posts into this thread to keep the forum organized. 

The Studio and the Origin team are looking into this right now, we will update you when we have more information at hand. In the meantime, and if you are a bit tech-savvy, you might want to try the workaround posted by ston3cold in this thread: http://answers.ea.com/t5/Battlefield-1942/Battlefield-1942-Invalid-Serial-Key/m-p/175664#M50

Thank you for your patience.

This FAQ should help:

Hmmm, I uninstalled BF1942. I removed anything to do with the Registry fix that was supplied. Re-downloaded and Origin installed the game.

Still getting the "Invalid CD Key" error. So I did the "Repair Install", although I figure a fresh install would already include the fix...

Still getting the "Invalid CD Key" error.

BTW the server I was trying to connect to was one of the EA - US East - PUBLIC - Mult

I tried a few servers under the EA - US East - PUBLIC - Mult.

I did FRAPS the event. and will post on Youtube so that we can see the issue.

Just call origin i got the number 1-855-674-4461

There is a problem with having to call EA for the key... if it's free the key should no longer be required, period, and all checks against should be completely removed.

The registry edit option doesn't work because there's no registry key in there!

And without a registry key that SHOULD be in there the ereg software is useuless.

So EA/Origin admits there is a problem with the Digital release of BF1942?

YES!!! This worked! Thank you VERY much for this fix! How you, or anyone, found this out is amazing. 🙂

THANK YOU!

thats allverywellbut where do you getthe origin game client ?.. for installed games

This solution doesn´t work for me.... what can i do?

i found that going to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Electronic Arts\Origin\Battlefield 1942\ergc (FOR 64bit OS)
and modifying the ergc file by copying and pasting your key. in stead of making the new folders worked as well.

It still doesn't work. The error message comes up in a different box (I think) but it still says Error Invalid CD Key. I am using Windows 7 64 bit, if that makes any difference

I can't find my CD key
