If you have a AMD or Intel GPU go here > Download PhysX > Install > Restart the PC > Test

If you have a NVIDIA GPU and you have the latest driver installed, go here > Download PhysX > Install > Restart the PC > Test.

If that don't helps, create a DxDiag in text file format and post it with your next reply. You can do that with the "Choose file" button at the bottom right corner of the reply window. 

That don't helps.

• Go to your ......\Dragon Age II\__Installer\directx\redist\ folder.
• Delete all files with the "*.cab" file extensions. (Only the files with the "*.cab" file extensions!!)
• Run the "DXSETUP.exe" in that folder as Administrator. (Right click the exe > Run as Administrator.
• After the installation ist finished restart your PC.
• Test.

It didn't help, the problem remained the same. Dragon Age 2 does not start, but NFS Heat does. Which is also purchased on Steam. 

Thanks, finally someone helped me. Now I can play DA2
