Some features of the Windows Script Host require the Windows Script Host version 5.6. ITScriptNet ships with the installation for the Windows Script Host 5.1.

Features that are not supported in version 5.1 include WScript.Shell.

If you need these features, you should download and install the Windows Script Host version 5.6 from http://www.microsoft.com/scripting.
