Duplicate CD Key

 

If you purchased a new retail game and are receiving Duplicate CD Key error, please contact the retailer where the game was purchased to obtain a new copy of the game.

If the retailer is unable or unwilling to assist you, it is recommended that you contact the game's support for further assistance.

 

Important:

A retail CD Key may only be registered to one Steam Account. CD Keys are associated with your Steam Account, not the computer on which the game is installed.

Please see the Resetting a Lost Password article for instructions to retrieve your lost Steam account if it is possible that you have registered your CD Key in the past.

Failed to Contact Key Server

This error most often occurs when there is a communication problem between the computer and the Steam network. Even if browsing the Internet has no issues, there may be an issue or program blocking Steam functionality.

Possible Causes

Upon trying to launch a third-party title on Steam, you may experience this error. The most common causes of this issue are listed below:

If the game is a recent release, or was purchased during a sale

While we do our best to anticipate demand from our users, occasionally we may run out of keys to provide for your purchase. When we are out of keys, this error will appear. You will be issued a key as soon as we have been given more by the game's publisher.

 

Using an Incompatible Operating System

If you are trying to run the game, or view the CD Key for a game, while using an operating system on which the game has not been released (i.e. attempting to run a Windows-only release while using the Mac OS X Steam client), then you may receive this error. To determine which operating systems a title is available on, please see the Steam store page for information.

 

Router Configuration

Some third-party games may require the opening of additional ports on your router in order to work correctly. We recommend following the Using a Router with Steam guide for initial troubleshooting.

 

Firewall

Your firewall might be preventing the game from working correctly. We recommend following the Using a Firewall with Steam guide for initial troubleshooting.

 

Problem Occurs After Updating Steam

If this problem occurred directly after a Steam update and the firewall is already disabled, please try this process:

  1. Log out and exit Steam
  2. Navigate to C:\Program Files\Steam (the default location). If you have installed Steam to a different folder, please locate that folder now.
  3. Rename the file "ClientRegistry.blob"  to ClientRegistryOld.blob and then close the Steam folder
  4. Launch Steam and login. Steam should update, re-create the file, and then you will be able to play

 

Connection Trouble

If you are currently experiencing intermittent connection problems, you may also experience this error. Please contact your Internet Service Provider to make sure there are no current outages in service at this time.

Game Not Available In Your Territory

You will receive this error message if you have purchased a regionally restricted copy of the game and attempt to use the game in a different region.

If you purchased a regionally restricted game and you do not live in that designated region, you must contact the seller for a refund.

Note: Regionally restricted games will be noted as such on their packaging.

 
Recent Releases

You may see this error message with some recent releases.  Please check the Steam Store page to see if the game has been released yet for your region.

Invalid CD Key

 

CD Key Information

Your CD Key will be either 13, 15, 18, or 25 characters long - the "S7160880" code which appears on some CD Key stickers (after the CD Key) is a part number and is not part of the CD Key.

 

Note:

Only the retail games listed here can be registered through Steam. No other retail games can be registered and downloaded using Steam.

 

Errors While Entering Your CD-Key

If your CD-key matches the XXXXX-XXXXX-XXXXX-XXXXX-XXXXX pattern, please note that some numbers and letters will not be used as part of the CD Key code:

  • The number 0 (try entering the letter Q or D instead)
  • The number 1 (try entering the letter I instead)
  • The letter O (try entering the letter Q or D instead)

Check instances of the following pairs to ensure these characters are not being confused:

  • The letter B and the number 8
  • The letter G and the number 6

 

Games for Windows Live

You may be entering in a CD Key that needs to be added within the Games for Windows Live interface instead of through the Steam client. A list of current Games for Windows Live titles on Steam can be found here.

 

Third party games purchased via Steam

CD Keys are issued with many third party games.  In many cases, Steam will display your CD Key when you first launch your game.  If your game launches and asks for a CD Key you do not have, please try the following:

  1. Right-click on the game in the Library tab and select View Game CD Key. This option is not available for all Steam games and a CD Key is not required for all games.
  2. Verify your GCF files.  Follow the directions in the Verify Integrity of Game Cache section of the Verify Game Cache Files (GCF) article. 
  3. For Windows Vista users, follow the directions under Try Running Steam as Administrator in the Windows Vista Troubleshooting article.  Then, verify your GCF files again and test the issue.
  4. For Windows XP users, on rare occasions you may need to properly set registry permissions: 
     
  • Exit Steam.
  • Go to the "Start" menu, select "Run", type "regedit" and click "OK".
  • Navigate to the following registry key: HKEY_CURRENT_USER\SOFTWARE\VALVE
  • Right click and select "Permissions"
  • Check the boxes for "Admin" and "System" to "Full control" and "Read".
  • Restart Steam and then verify your GCF files again.

 

Just Cause 2

If you are seeing this issue with a Just Cause 2 Retail CD Key, please check your CD Key and enter any listed O's or 0's as a Q to activate your product.

 

Empire: Total War

Empire: Total War shipped in many retail boxes with 2 CD keys, one key is printed on a slip of paper and is a key to unlock extra units in-game. The second key is for the game itself and is printed on the back of the manual. If you enter only the extra units key then try to install ETW, you will receive an error that directs you to this article. Please find the other CD key printed on the manual and enter it. After you have activated this key, you can finish your install and play the game.

This issue may also affect some D2D customers as D2D originally did not issue all users both keys and some users only got the extra units keys. If you are a D2D customer you should now be able to find both keys at their website if you initially only got one and should have had two.

 

Dark Messiah Might and Magic

If you consistently receive an Invalid CD Key error when trying to register Dark Messiah of Might & Magic, try re-entering the CD Key backwards, digit for digit.  If you continue to have difficulty, please contact Steam Support.

 

Football Manager 2009

You may have trouble deciphering some characters in the license key on your Football Manager 2009 packaging. Characters O and 0 as well I and 1 are printed in a very similar manner.

 

Opposing Force CD-Keys

Opposing Force CD-keys cannot be registered through Steam. Opposing Force was included in a retail Half-Life package. The Half-Life CD-key included in the package will unlock all of the games included in that package, including Opposing Force.

Retail / Digital CD Keys

 

What is a CD key and where can I find it?

The CD Key is a serial number with a combination of 13, 15, 18, or 25 letters and numbers - it can be found on a sticker inside your game's case or printed on the game's quick reference card.  For authorized online resellers, where no physical media is shipped, the CD Key is usually included in an emailed purchase receipt.  For questions on who is an authorized reseller, please contact the publisher for a list of their authorized resellers.

The CD Key acts as your proof of purchase for the game - Steam Support may ask for it if you need to establish your ownership of an account. It is recommended that you keep your CD Key in a safe place to ensure the security of your account.

Opposing Force CD-keys cannot be registered through Steam. Opposing Force was included in a retail Half-Life package. The Half-Life CD-key included in the package will unlock all of the games in that package, including Opposing Force.

Note: Only the retail games listed above can be registered through Steam. No other retail games can be registered and downloaded using Steam.
