Remarks
A custom action that is written in JScript or VBScript requires the install Session object. The installer attaches the Session Object to the script with the name "Session". Because the Session object may not exist during an installation rollback, a deferred custom action written in script must use one of the methods or properties of the Session object described in the section Obtaining Context Information for Deferred Execution Custom Actions to retrieve its context.
