How the Installer Resolves Parameters

Parameters used in a PIF product are resolved by the Installer during installation of the product on the target computer. Following are the steps the Installer performs, depending on the type of installation.

New installation
  1. Reads default parameter values defined in the PIF product.
  2. Reads parameter values from a response file.
  3. Reads parameter values from an installation dialog (installation path can be modified).
  4. Reads parameter values from the existing environment (unattended mode).
  5. Reads parameter values changed after execution of the product-specific pre-install script.
Reinstallation

Reads parameter values from the previous installation (installation path cannot be updated).

Update installation
  1. Reads default parameter values defined in the PIF product.
  2. Reads parameter values from a response file.
  3. Reads parameter values from the previous installation.
  4. Reads parameter values from an installation dialog (installation path cannot be updated).
  5. Reads parameter values changed after execution of the product-specific pre-install script.
