Call JScript From Property

This custom action runs JScript code that is stored inside a Windows Installer property.

You might store the script in a property if part or all of the script needs to be generated

dynamically based on end user input or system configuration.

Tips

! The script is limited to 32 Kb, which is the size limit for Windows Installer properties.

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

! 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.

! Property

Specify a property that stores the script, either by selecting a property or typing a

new property name. Elsewhere in the installation, you must provide a mechanism for

populating this property with the script text.

! Script Function Call

(Optional.) Type the name of the function within the script to call.

! 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.)
