Where MAPIMAIL.VCX class comes from? Check Special requirements in MapiMail.chm in MAPI Mail Class Download #9524

>I am attempting to use the MAPIMAIL.VCX class. When the SENDMAIL method is executed, the Windows installer pops up as tries to install something from the VFP9 install CD. Does anyone know what is trying to be installed or how I can find out. I need to know so that I can include it in my install package for the application. TIA.
