During the installation of Spectrum on Windows, if the Windows Messaging Subsystem or Messaging Application Programming Interface (MAPI) subsystem is not installed, you will get the following error during Host Evaluation portion of the installation process:
Warning: Windows Messaging has not been configured correctly.
You must set your default mail profile to enable email for SPECTRUM applications.
The Windows Messaging Subsystem is only used by the Spectrum Performance View pviewrep application to e-mail the Health Report created by the pviewrep application.
If the pviewrep application is not going to be used, there is no need to configure Windows Messaging and the installation can continue.
If the pviewrep application is going to be used, the installation can continue but the Windows Messaging will have to be configured before using the pviewrep application.
The pviewrep application is discussed in the "Run Health Reports from the Command Line" section of the "Performance Administration Guide".
