Oh sorry, I put the download link, my mistake. It's this page https://www.nvidia.com/Download/index.aspx
I found it on this other discussion https://answers.ea.com/t5/Dragon-Age-Origins/DA-O-Invalid-license-Reason-code-Missing-DLL-NxCharacte...

What's worse is that program (EDIT: PhysX) isn't usually installed by advanced users and is in fact, full of Nvidia telemetery.
You normally don't have to change the launcher manually, that is not the intended behaviour, sometimes shit happens.
Despite being completely OT in this thread, I consider me a pretty advanced user, and I install PhysX all the time. 😁 😉
To the problem:
Some games, like DA:O, need the PhysX library to be installed to work, so you either install PhysX or you don't play the game.
As a matter of fact this PhysX library's are normally installed with the game, only if this installation process failed you need to install them separately.
So if the installation of the PhysX library failed you should have a look at your system. Overprotective virus scanners or missing permissions could be a reason.
Btw, the stand alone Physics installation packed from NVIDIA (https://www.nvidia.com/en-us/drivers/physx/physx-9-19-0218-driver/) is not containing Telemetry. The NVIDIA Telemetry is in the the Driver installation package that you don't need if you have a AMD Graphics card.
There are ways to disable the NVIDIA Telemetry without getting ride of PhysX, just google them.
If you have further questions about PhysX, please create a new thread.
