3. In the blank area under the Destination Folder group box, right-click and select
Add > Checkbox.
The Properties for Checkbox dialog box appears, where you set a property and
control text associated with the check box.
4. In Control Text on the Control tab, enter:
Put installation under the Common Files folder
This is the text label for the check box.
5. Click the New button to the right of the Property drop-down list.
The Property Details dialog box appears, where you create a new property to hold
the value of the check box.
6. Complete the dialog box:
a. In Name, enter COMMONDIR (all uppercase).
b. Leave the Value field blank.
The check box value must evaluate to blank (nothing) initially so that the check
box is not marked when end users first see it.
c. Leave the defaults in the remaining fields.
d. Click OK.
Note
Technically, leaving a property blank is not allowed according to Windows Installer
guidelines, but in this tutorial, you leave it blank so that the check box is initially
unmarked. Because the property value is blank, the property does not appear under
the Properties icon in Setup Editor > Product tab.
7. Click OK on the Properties for Checkbox dialog box.
The check box appears on the Destination Folder dialog box.
