Name: install_acs_32

Syntax:
install_acs_32 [/Exclude=<function1,function2,...> | /Reset | /Q]

Description:
Installs or upgrades IBM i Access Client Solutions (ACS).

If no parameters are specified:
- an existing installation will be upgraded.
- and this is a new installation, the user will be prompted and allowed to customize the installation.

Note: If the source location of the product files was already customized using the /AdminConfig parameter, that configuration will be used for new installations and upgrades.

Optional parameters may be specified:

/Exclude=<function1,function2,...>
- specified functions will be excluded.
See /PLUGIN=RESTRICT in GettingStarted for a valid list of functions which can be excluded.
Note: This parameter will be ignored if the administrator has used /AdminConfig.

/Reset
A new installation will overwrite the current installation and will be customized based on user input.
Note: This parameter will be ignored if the administrator has used /AdminConfig.

/Q
Do not display installation completion message.
