First, verify that your computer has the correct disc reader. Some of our software comes on a DVD-Rom disc, which cannot be read by a CD-Rom reader.

No. Once the Atlas is installed, you should not need your disc and you should not need to be online. We strongly suggest keeping your disc in the case somewhere safe. Should you need to reinstall, they will both be necessary.
