Long Machine ID format in the VRS 4.x License Activation Utility


QAID # 7968 Published

Question / Problem:

Why does the VRS 4.x License Activation Utility recognize such a long format for the Machine ID?

Answer / Solution:

There are two forms of machine ID in VRS 4.x:  The MAC address of the Network Interface or a GUID (Globally Unique Identifier).

The MAC address is used by default in VRS 4.x and uses the format: xxxx-xxxx-xxxx.  

A GUID has 32 digits with 4 dashes in the format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.

In VRS 4.x, the GUID is used only when there is there is no network interface or when the network interface has been disabled at the time that the license was activated.

In VRS 5.x, a GUID is always used as the Machine ID.  So the Machine ID in VRS 5.x always uses the format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.
