Hello,

if you have a Matrix installation you need to use the DLC installer to enter your codes,

also you can use your codes on Steam to redem your keys and license the DLCs through Steam.

1. Download the last update file CMO-UpdateComp-v1.08.1674.zip for Command: Modern Operations from your account's download area. (*)

2. Once you have finished downloading the file, please unzip the downloaded file to a folder in your Hard Disk.

3. Run the extracted file.

4. If you have already installed CMO-UpdateComp-v1.08.1674.zip a window will say "You're already up-to-date". If not got click on "Next" and go to step 7.

5. Find a button named "Activate DLC"

6. Agree to License Agreement and click "Next".

7. When asked to insert the serial number, please click in the drop down menu "Select a New Product to Install... " and select "Command Modern Operations: Fail Safe".

Type your "Command Modern Operations: Fail Safe" serial number.

8. Click in the button "Check Serial".
You should see then the name "Command Modern Operations: Fail Safe" being added to the list of games displayed in the box named "Setup as detected a valid serial number for:".

9. Repeat steps 7 and 8 for activating your other DLC.

10. Click in the "Next" button in order to proceed with the unlocking of your new DLCs.
