How to install/enable ktpass.exe on Windows 7?

Unfortunately the answer is that keytabs for Kerberos cannot be generated on Windows 7. It must be generated using the ktpass utility on a Windows Server OS.

The Keytab must be generated on either a member server or a domain controller of the Active Directory domain using the ktpass.exe command. Use the Windows Server built-in utility ktpass.exe to create the keytab. The ktpass command must be run on either a member server or a domain controller of the Active Directory domain. Further, Keytabs must be created on a Windows Server operating system such as Windows Server 2008, 2012, or 2016. Keytabs cannot be created on a workstation operating system, such as Windows 7, 8 or Windows 10
