This Installation Code combines the Volume ID, MAC address and Hostname. The combination of the several installation codes makes it significantly more difficult to configure virtual machines with identical hardware IDs.
Pros/Cons
+ Cheating is extremely difficult due to the 3 used parameters
+ If an image tool is used, the MAC address is still different
+ Good within a network because the MAC address must be unique
+ Works in single user and network environment
- Needs more often a re-licensing because of hardware changes
- See considerations above for multiple network cards
- Restricted use in network environment with Windows 98 / NT machines
- Allows to install the application multiple times on the same server
Recommendation
•Should be used for environments were heavy copy protection is needed and several installations on one machine should be possible. Otherwise use installation code 8.
