Title
Using a Property as the Name for an IIS resource in the Internet Information Services View

Summary

When using Windows Installer properties to set IIS resource names dynamically at installation run time, IIS configuration on the target machine will fail if the property used for the name does not have a value.

Synopsis

When using Windows Installer properties to set IIS resource names dynamically at installation run time, IIS configuration on the target machine will fail if the property used for the name does not have a value.
NOTE: This problem will occur even if the IIS resource belongs to a Component not selected to be installed.

Discussion

This problem can occur if the property used for the IIS resource name is not defined in the install project, but is left to be defined at runtime, such as by a value entered by the end user through an installation dialog.
If the property has not been initialized, a verbose log of the install will show an exception during execution of the ISIISInstall action. For example, if the property was used to name the Default Website, the following exception will be in the log:

Exception caught in ProgressMessage for sMessageToFormat 'PROGMSG_IIS_CREATEWEBSITE' and the following sStringToInsert: Default Website


Workaround

This problem can be avoided by assuring that the Property is initialized. This can be accomplished in several ways, for example:
  1. Add the property to the Property Manager table, which requires a default value in the value column.
  2. Schedule a 'Set Property' Custom Action to run before the ISIISInstall action.
NOTE: If the property is set with a custom action during the Install UI Sequence, add the property to the SecureCustomProperties property value in the Property Manager table.
