MAC Address instructions:
Please go to:

Start (Windows Icon)>Windows System>Command Prompt

type: "getmac" then press enter.

We need to know the active TCP/IP adaptor Physical Address.
Example output with device specific details removed:

Physical Address Transport Name
=================== ==========================================================
xx-xx-xx-xx-xx-xx Media disconnected
yy-yy-yy-yy-yy-yy DeviceTcpip_{gggggggg-gggg-gggg-gggg-gggggggggggg}
zz-zz-zz-zz-zz-zz Media disconnected

The Physical Address listed for the "DeviceTcpip_" Transport Name is the required address for the form.

Once your license is issued it is difficult to rehost - so to check and conform the ID please take a screen shot of the "getmac" output and we can confirm the ID from that if needed
