Installing Orca

Orca could be installed to one's system after finishing installing the Windows SDK.

Installing Orca
While Orca is included in the Windows SDK, it is not installed by default; instead, the MSI Package for installing Orca, is found at the Windows SDK directory.

Launching the Installer
Therefore, to install Orca, the CMD Shell (not to be confused with the command prompt found on default Microsoft Windows installations) is opened. To open the CMD Shell from the start menu:

START MENU\All Programs\Microsoft Windows SDK\CMD Shell

On opening the CMD Shell, type the following command:

orca.msi

Continuing with the Installation Process
After proceeding through the installation steps, choose the complete installation and install all components of Orca. For Windows Vista users, the User Account Control prompt will appear during the installation asking you to allow elevated permissions, choose allow.

Orca could now be found in the Start Menu.
