Call JScript From Embedded Code

This custom action runs JScript code that is embedded inside this custom action.

Tips

! The script is limited to 255 characters; use other JScript custom actions for longer

scripts.

! The destination computer must contain the script’s runtime.

Usage

Double-click the custom action and complete the Details tab:

! Custom Action Name

Enter a unique name that begins with a letter or underscore. It can contain numbers

and periods. It must not match the name of any Windows Installer standard action.

See Standard Actions Reference in the Windows Installer SDK Help.

! Run Script in Win64 Process

Mark this if the script file is 64-bit. If the script file is 32-bit, leave this cleared.

(Available only in 64-bit installations.)

! Enter the JScript to execute

! Type or paste the script text. Code elements, such as function names, declarations,

and values, are color-coded. You can use bracketed property names, table keys,

environment variable references, and other special substrings. See Formatted in the

Windows Installer SDK Help.

Call JScript From Installation

This custom action stores a JScript file in the Binary table of this installation file and runs

it during installation. During installation, the JScript file is extracted to a temporary

directory, is run, and is deleted.

Tips

! Manage the file on the Resources page, which reflects the Binary table.

! Use the script to read and write properties to the installation.
