I just searched for it in Device Drivers forum and found a
solution I think.
1. Extract the file using
CODE
setpoint301.exe /extract_all:C:\SetPoint
2. To create the response file, run
CODE
C:\SetPoint\setup.exe /r
3. Copy the response file from "C:\windows\setup.iss" to "C:\SetPoint"
4. The silent install can now be done by running
CODE
C:\SetPoint\setup.exe /s
As I use an AutoIt script for installing SetPoint 3.01, I didn't test this yet.
