Acrobat 6 is extremely old and not likely to work properly on any current computer.
As was explained before, chances are pretty good that your Acrobat 6 will not run on your new computer. However, what you would do to at least try to install it is to go to a computer that does have an optical drive, and copy everything from the installation medium to e.g. a USB flash drive. You can then install from the USB drive.
