Hostid

The Hostid is required for the licensing process and here is how to get it:

Windows

• Run the "Command" (cmd.exe) application.
• Enter ipconfig /all
• Copy down the "Physical Address" (aka "MAC address") from the "Ethernet adapter Local Area Connection" (or "... Wireless Connection") section. 
• The hyphens between the two-digit blocks are not necessary.
• All addresses shown here are examples and have to be replaced through your actual address!

macOS

• Open the "System Preferences" and go to "Network"
• Select an ethernet port and click on More Options... > Hardware. If your computer does not have an ethernet card, try WiFi instead.
• Copy down the "MAC-Address" code for the licensing process.
• The colons between the two-digit blocks are not necessary.
• All addresses shown here are examples and have to be replaced through your actual address!
