Chapter 18: Additional Installation Options
Accessing the Serial Number During and After Installation
When an end user enters a serial number in the Customer Information dialog, it is passed to your .dll file
for verification. If the serial number is successfully verified, the installation can continue. If the serial
number is invalid, the installation will end, depending on how many retries you allow in the Retry Limit
field.
Note: InstallShield sequences the serial number .dll file custom action after any user-defined custom actions. Thus, if you
add your own custom action and schedule it after the Customer Information dialog, the installation launches this custom
action before the serial number .dll file custom action.
Accessing the Serial Number During and After
Installation
The Windows Installer property that stores end user’s entry for a serial number is called
ISX_SERIALNUM. If you select Yes for the Show Serial Number setting for the Customer Information
dialog, the serial number field is included on this dialog, and Windows Installer sets the property to the
serial number that the end user enters at run time.
During Installation
During installation, you can access the value of ISX_SERIALNUM by using code such as in this
VBScript sample:
' Get the value of Serial Number
Dim sSerialNo
sSerialNo= Session.Property("ISX_SERIALNUM")
' Show it.
MsgBox sSerialNo
Important: If you want to be able to access the value of ISX_SERIALNUM after the installation, your installation must
store the ISX_SERIALNUM value on the target system somewhere. For example, in the Registry view, you could create a
registry key that adds a value that uses [ISX_SERIALNUM].
After Installation
Following installation, you can access the serial number if your installation wrote the value of the
ISX_SERIALNUM property to the target system. For example, if your installation wrote the value to
the registry, you can write code that checks the registry for the serial number.
