.NET Framework installation
To send messages through SMTP, you must have access to the Microsoft .NET Framework runtime version 2.0 or later for Pathway. The Microsoft .NET Framework version 2.0 (x86) redistributable package or the installer for a later version of the .NET Framework should be used to set up the .NET runtime on the PDF background job queue machine if the new Pathway Emailing module is to be used to send messages in HTML format.
You can access the various installer packages from the Microsoft Download Center, which is found at http://www.microsoft.com/downloads/en/default.aspx.
