I bought a music interface (Komplete Audio)…It came with Cubase LE6 but I do not have a disk drive to install the software. Is there a location where I can down load the software for My MacBook Pro?
Create a mySteinberg account and register the software there. I can’t remember but that might create a downloadable file link or you might have to contact support to explain your situation and request it.
Regards 
Thank you for your reply…
I do have a mySteinberg account and I did contact support. This disk does not have an activation code or serial number it is just software that is packaged inside the Audio Bundle I purchased. I have seen other post here on the forums and Steinberg Support had replied to them with the download link for the .iso file for the Cubase LE version
Best,
