 If during the NetcamViewer installation, the error message "opening file for
writing C:\Windows\sytem32\LibPMD.dll" is always popped, kindly please
turn off all browser windows, include CDWizard application, and then try

So before NetcamViewer installation, please make sure there's no "iexplore"
