I'm a technician for a college, and have been tasked with trying to get two rather old pieces of machinery up and running.

We have a 1996 Novamill

And a 2004 Microrouter Pro
download/file.php?mode=view&id=4813
I have to admit, I have little idea on what I am doing in order to get these running

The software we have is:
VR CNC Milling V2.25
Quick CAM 4D Milling V1.3
Quick CAM 3D Milling V2.2
VR Robot V1.1
VR Cim V1.1
MillCAM Designer
2D Design V1 + Denford Extention
I have purchased a parallel to usb extension cable, but alas the software still does not recognize the attached dongles. A floppy to usb drive is also on it's way in an attempt to locate the license files.
What I would like to know is, which of the software is actually necessary to run the machines? If I can get the lisences from either the dongles or floppy disks, what would I do next? And if I cannot get the licenses from these, what can I do?
Any help is greatly appreciated, and please do not fear that you would be patronising in anyway! And please ask if I have left vital information out.
All the best,
Charlotte
