MCHPFSUSB Files

I've downloaded CDC_RS232_Emulation.EXE from microchip.com and unzipped it. The Read me file shows which files were unzipped, between them there is a folder called "PC", which has among others "PDFSUSB.exe". The problem is that i couldn't find neither that folder nor PDFSUSB.exe nor the other files that should be inside that folder.
Did anyone had that problem? Does anyone know how to solve it? Everywhere I look in internet says that the documentation and all stuff is available from microchip.com.

thanks
