To build an installer for the Sassafras Software’s K2 – Keyserver Key Audit client use the client customization application they provide.  This is found in the
“client – misc”  folder of their computer installer archive that can be reached by logging into their Support and Downloads web page.

Their documentation…

I put the client installers and the k2clientconfig application in the same folder and the ran this command:

k2clientconfig.exe -s 3 -c no -b no -h keyserver.williams.edu k2Client-x64.exe

The output was:

Changing PROP_SILENCE
Changing PROP_HOSTNAME from ‘keyserver’ to ‘keyserver.williams.edu’
Changing PROP_KEYCHECKOUT from ‘2’ to ‘0’
Changing REBOOT from ‘Force’ to ‘Suppress’
Digital signature has been removed from k2Client-x64.exe
