By using the Chaos installer for automatic installation with the respective options for that (-auto or -quiet=1), or otherwise installing a Chaos product, you accept the Chaos End User License Agreement and the Chaos Global Consumer Privacy Policy.

Specifies whether to use the Graphical User Interface or the command-line one. (default: 1)

-debug=<level>

Specifies the level of debug logging used by the installer. (default: 0; assumes the value of 1 if the argument is provided with no value)

-auto

Enables automatic installation and forces -quiet.

-quiet=0/1

Specifies whether the automatic installation is quiet or not. (default: 1 when -auto is present; otherwise 0)

-backup=0/1

Specifies whether the installer should perform a backup. (default: 1)

-bin=<filename>

Specifies the path to the binary image containing compressed installation data to be used for the current installation run.

-binaryOffset=<offset>

Offset in bytes of the binary image - to be used with packed installation executables.

The filename of an install log to be used for performing the uninstallation. No uninstallApp required.

-uninstallApp=<name_of_application>

The name of the application to be uninstalled by the installer.

-ignoreErrors=0/1

The installation process ignores errors during the installation and behaves as if the process completed successfully.


Note: If you perform an automatic installation and using the Software, you accept the terms of the End User License Agreement and the Global Consumer Privacy Policy, which are available to you when running the installer in GUI mode or at https://www.chaos.com/. If you do not accept these terms, do not install or use the Software.

Usage: <installation_file> {<option>} where option (case-insensitive) is one of the options listed above.

Example (Silent Installation):

  1. Open Command Prompt (CMD)
  2. Navigate to the folder containing the installer:

Code Block
cd "C:\Downloads\Corona"

Run the silent installation command:

Code Block
.\chaos-corona-installer.exe -auto -gui=0
 Uninstaller only:
ParameterDescription

-uninstallApp="Chaos Corona for 3ds Max"

Runs the uninstallation for the specified application.

-log="<path>"

Specifies the path for writing the uninstall log file.

-gui=0 

Runs the uninstaller without a GUI (silent mode).


Example (Silent Uninstall):

  1. Open Command Prompt (CMD)
  2. Navigate to the uninstaller directory:

Code Block
cd "C:\Program Files\Chaos\Corona\Corona Renderer for 3ds Max\uninstall"
 
Run the silent uninstallation command:

Code Block
.\installer.exe -uninstallApp="Chaos Corona for 3ds Max" -log="install.log" -gui=0

Corona 12 and older: 

ParameterDescription
-h or --helpDisplays command-line help.

--acceptEulaAndAutoInstall

Runs the installation in console mode with no user input. It is the same as running the typical installation option in GUI, accepting the EULA, and finishing the installation process.
Important note: 
Currently, there is no way to specify which items should be installed during silent installation. This means that when Corona is already installed, the installer will remember the last items selected by the user (e.g. which 3ds Max versions were selected, what additional components were selected). If you uninstall Corona and run the installer in silent mode, it will use the default behavior - it will detect which versions of 3ds Max are installed and will install all additional components.
