How to install the NVIDIA GPU AI Denoiser in offline mode?

In Corona Renderer 3 or newer, our universal installer attempts to download and install the NVIDIA GPU AI Denoiser automatically, provided that a supported NVIDIA graphics card is detected. This is however sometimes unwanted or impossible - for example in the case of batch installing Corona Renderer on a render farm. In such cases, the denoiser package can be downloaded once and then distributed along with the installer. 

Note: The NVIDIA AI Denoiser is no longer downloaded separately when using Corona Renderer 7 and newer. Each new denoiser version is provided by NVIDIA through a GPU driver update.

Here is how to install the denoiser manually:

1. Download the universal installer for 3ds Max or Cinema 4D here - https://corona-renderer.com/download/
   
   
2. Download the NVIDIA AI Denoiser package for:
   • 3ds Max:
     • For Corona Renderer version 7 and newer:  The NVIDIA AI Denoiser is no longer downloaded separately. Each new denoiser version is provided by NVIDIA through a GPU driver update.
       
       
     • For Corona Renderer version 6: https://installer.corona-renderer.com/3dsmax/6/NvidiaAiDenoiser
       
       
     • For Corona Renderer version 5: https://installer.corona-renderer.com/3dsmax/5/NvidiaAiDenoiser
       
       
     • For Corona Renderer version 4: https://installer.corona-renderer.com/3dsmax/4/NvidiaAiDenoiser
       
       
     • For Corona Renderer version 3: https://installer.corona-renderer.com/3dsmax/3/NvidiaAiDenoiser
       
       
     • Note: The NvidiaAiDenoiser file does not come with an extension! The file name should be just "NvidiaAiDenoiser" and this is correct. There is no need to rename or unpack this file!
       
       
       
   • Cinema 4D (works with all versions of Corona Renderer):
     • For Corona Renderer version 7 and newer:  The NVIDIA AI Denoiser is no longer downloaded separately. Each new denoiser version is provided by NVIDIA through a GPU driver update.
       
     • https://installer.corona-renderer.com/c4d/3/NvidiaAiDenoiser
       
       
     • Note: The NvidiaAiDenoiser file does not come with an extension! The file name should be just "NvidiaAiDenoiser" and this is correct. There is no need to rename or unpack this file!
       
       
       
3. Place the downloaded NvidiaAiDenoiser file next to the universal installer (e.g. if the universal installer is located in C:\Downloads, then place the NvidiaAiDenoiser file in C:\Downloads as well):
   
   
   
4. Run the universal installer and proceed with the standard installation.
   Note: There is no need to use the "Custom" installation type, or to check or uncheck any options. This will work even if you simply press the "next" button a few times to finish the standard installation.
   
   
5. The universal installer will install the NVIDIA GPU AI Denoiser from the local folder instead of downloading it.

Note: If you do not see NVIDIA AI Denoiser in your host application it is likely that your graphics card is not supported. See: Hardware Requirements

The NVIDIA GPU AI Denoiser installation can be also safely cancelled, or skipped completely - See: How to install Corona Renderer without additional data?
