Hi,
welcome @forums.autodesk.com
>> I have the autocad disc but my disc drive isn't working anymore.
>> Need it urgently for work
Besides of missing informations (plain AutoCAD or vertical product, or LT, what language, ...) I would guess it will not be easy to get the files now and from any other user here.
The most simple options might be
a) use another computer to copy the installation media to a USB-disk or to the network so you can use it on your system
b) buy a DVD for a few US$ and connect it to your USB drive if you can't built it into your workstation.
Good luck, - alfred -
