Possible fix for DLC not showing up in game with Origin installation. Note: Affects owners of the RETAIL version

I was able to get the in game downloader to download my DLC. However the DLC stone prison, wardens keep and return to ostager would not trigger in game even though they were enabled.

I was able to get return to ostager and stone prison working by doing the following (http://answers.ea.com/t5/Dragon-Age-Origins/SOLUTIONS-UNAUTHORIZED-DLC-or-MISSING-DLC/m-p/470476/highlight/true#M1205):

"Enable Updater

If your Dragon Age Updater is not starting when your system starts, you may need to change the service settings to enable it. To ENABLE the Dragon Age Updater:

1. Run “services.msc” from the Run menu option in Windows. Pressing the Windows key + R will bring up your Run menu. Simply type "services.msc" into the window and click OK. (NOTE: “Services.msc” controls essential components of Windows. Errors in configuration can prevent the system from operating correctly. Any changes you make in services.msc are made at your own risk.)
2. Find the Dragon Age: Origins Updater service in the list.
3. Double-click on the service to bring up the properties.
4. Press the Start button if the service is not currently running.
5. Change Startup type to Automatic.
6. Close the Properties and Services interface."
   
   
   

However it did not get wardens keep to work and i could not find Levy Dryden to appear at base camp.

To get Wardens keep to work I did the following (http://answers.ea.com/t5/Dragon-Age-Origins/Return-to-Ostagar-not-Triggering/td-p/3065340):

"I searched for many hours to find a solution for this problem and I got nothing!

Except that I learned about that XML files are important! So I tried this and it worked!

I will give you an example for the Return to Ostagar DLC!

I downloaded the Return to Ostagar File and the Return to Ostagar Offer file on the Bioware Social Network.

These files should now be located in the download section.

DAO_PRC_CP_1_1.1.DAZIP (Return to Ostagar)

DAO_PRC_OCP_1_1.1.DAZIP (Return to Ostagar Offer file)

I then opened the DAUpdater (I just typed DAUpdater in my start menu) and then click Select DAZIPs and located the files in your download section

and click install selected and make sure there are no errors.

OK NOW! After this is done:

Go back to your download section

First Right click the DAO_PRC_CP_1_1.1.DAZIP (Return to Ostagar) file then > click 7-zip > click open archive. Now, drag and drop the manifest.XML file into the download section > now cut and paste this file by going to Documents > Bioware > Dragon Age > add-ins > dao_prc_cp_1 and then inside of this file paste the manifest.XML file!

Now time for the offer file! Go back to your download section Right click the DAO_PRC_OCP_1_1.1.DAZIP (Return to Ostagar Offer file) > click 7-zip > click open archive. Drag and drop the manifest XML file into the download section >Copy it and paste it in Bioware > Dragon Age >Offers> dao_prc_ocp_1 and paste it in there!

BOOM BA DA BING! The Bann Loren Lands should pop up on your Dragon Age map!

Do the same for The Stone Prisoner!

I hope this helps!"

Missing manifest.XML files causes problems with the DLC. Even though this example was for stone prisoner and return to ostagar it worked for Wardens keep.

Important points:

• Make sure you install the software 7-zip to be able to follow the above instructions. It took me a while to figure out what it was.
  
  
• DAZIP file can be found from the following website (http://dragonage.wikia.com/wiki/Downloadable_content_%28Origins%29)

• File names - dao_prc_ocp_1 - return to ostagar
                        DAO_PRC_CP_2 - stone prisone
                        DAO_PRC_NRX_1 - wardens keep
  
  

Hope this helps
