How do I find my hostid?
Some license files are "locked" to a specific hardware device, either a USB key, a
parallel prot key,
or a computer. This hardware device is identified by its
"hostid" (host identification). Depending on the type of hardware device, you'll
find the hostid in different ways.
Note that Activation licenses (introduced with GeoStudio 2012) do not use a hostid.
GetHostId Utility (Recommended)
The GetHostId Utility will detect all hostids on the computer on which it's run. This is
the simplest way to get your hostids. To run this utility,
attach your hardware key to your computer, then
click the link below and choose
GetHostId Utility v1.03
USB and Parallel Port Keys
USB and Parallel Port keys have their hostids printed on one side. A USB hostid will typically
start with "FLEXID=9-...". A Parallel Port hostid will start with "FLEXID=6-...".
MAC (Ethernet) Address
If a license is tied to an Ethernet card, the hostid is the Ethernet address. The Ethernet
address is composed of 12 hexadecimal digits (0-9 and a-f).
If you are using Windows NT, 2000, XP, Vista, Windows 7, or Windows 8, you can find your Ethernet address like this:
- Select Run from the Start menu, type cmd, and press Enter. A
command window is displayed.
- In the command window, type ipconfig /all and press Enter.
- Under the heading "Ethernet adapter Local Area Connection", your
Ethernet address is located next to the title "Physical Address".
If you are using Windows 95, 98 or ME, you can find your Ethernet address like this:
- Select Run from the Start menu, type winipcfg, and press Enter. The
"IP Configuration" window appears.
- Select your Ethernet card from the drop-down list.
- Look for the field labeled "Adapter Address". This is your Ethernet address.
(It should not begin with a "44-45" or "44-44".)
Sometimes a license is tied to a Composite Hostid, a special hostid that uniquely
identifies your computer. The easiest way to get the Composite Hostid is to run
the GetHostId Utility described above.
