I have a workaround to manually get Awakening installed.
Btw "...\Origin Games\" is where Origin places your installed games. By default, the path is "C:\Program Files (x86)\Origin Games\" on 64-bit Windows.
First, you will need to copy two folders into your Dragon Age install:
Copy "...\Origin Games\Dragon Age Origins Awakening\addins" to "...\Origin Games\Dragon Age\addins",
and "...\Origin Games\Dragon Age Origins Awakening\packages\core_ep1" to "...\Origin Games\Dragon Age\packages\core_ep1".
Now open a command prompt and navigate to "...\Origin Games\Dragon Age Origins Awakening\".
Type in the following command, but substitute your path to Dragon Age in /manifest:
DAO_UpdateAddinsXml.exe /addins="Bioware\Dragon Age\Settings\addins.xml" /manifest="...\Origin Games\Dragon Age\addins\dao_prc_ep_1\manifest.xml"
For example, a default install on 64-bit Windows command would be:
DAO_UpdateAddinsXml.exe /addins="Bioware\Dragon Age\Settings\addins.xml" /manifest="C:\Program Files (x86)\Origin Games\Dragon Age\addins\dao_prc_ep_1\manifest.xml"
Run Dragon Age: Origins and Awakening should now be in "Other Campaigns." I hope EA gives us a real fix soon.
This issue seems to stem from the update to1.05, as it's not one I had before. If so, I fear that this issue will have to be resolved by Bioware.
I have DX-11, and did not have any issues before installing the patch. It messed up Origins, as well, but I managed to get it functioning again on my own. I had to download the DLC I've purchased, via my Bioware account, and install them manually; after the patch, they stopped working properly.
