Example: Suppose you want to let the installation author set the attributes of a file

Enter the value to be substituted for the current value of the configuration item.
7. Click OK.
The Configuration Item Details dialog box lists the text and value you defined.

Specifying a Key for Substitution
When you add a configuration item to a configurable merge module as a key into a
table, you must specify a table for the key to make configurable. When adding the
merge module to an installation, the installation author selects from a list that appears.
For information on this format type, see Key Format Types in the Windows Installer SDK
Help.
To specify a key for substitution
1. Access the Configuration Item Details dialog box from the Module Substitution
dialog box.
See
Creating a Configurable Merge Module
on page 331.
2. Complete the Configuration Item Details dialog box.
See
Setting Configuration Item Details
on page 332.
3. From Type, select Key Into a Table.
4. Mark Delete Unreferenced Rows to have the row that is referenced by the default
value merged if the installation author selects the default value when adding the
merge module to an installation.
Example: Suppose the merge module includes a dialog box with a graphic. You
select Binary (Bitmap) from Key Table and set the Default Value to the bitmap in
the merge module. If the installation author selects a different bitmap when adding
the merge module to an installation, then the default bitmap is no longer
