How to copy software from cd to external hd

I would like to ask how to make extra copy of the software program from CD to my external HD. I have nero6. Can I use that program? How?
Thanks.

From My Computer with the CD in the drive-> Explore-> highlight the entire contents (Ctrl+a)-> then simply drag/drop the entire contents to new folder on your External. No software needed.

So is that it?.. after copying the software to my external HD can I install that copy on to another computer? Just like installing from CD?

Thanks…

Depends on whether the software needs the CD to be in the drive when starting/using the software.

If the software does a full installation and isn’t copy protected it’s as simple as suggested by MyticEyes.

Just copy all files and run the Setup.exe (or similar) on the other computer.
