The Philips SpeechExec Pro Dictate & Transcribe v6 SR1 is shipped on a DVD.  If you or your customer does not have a DVD drive, I would recommend loading it on a computer with a DVD drive, then copy the contents onto the PC without a DVD drive.
If you do not have any computers with a DVD drive, then you will need to download the software from our FTP site. 
We’ve uploaded the software into a folder on our FTP under eDist Download > Philips > Software.
