One very important note that should be included on the DVD packets.
1. First Copy the contents of the ArcGIS for Desktop 10.2.1 DVD to your hard drive.
2. Run esri.exe as Administrator.
If you don't do step 1 and try to run Setup from the DVD you will be repeatedly asked to insert Disk 1. You don't have a disk one so Installation cannot run to finish.
