I had such a hard time finding what some of the variables do in Setaid.ini because I don't have access to the deployment package part of SEMP (I know, most reasons are red tape in my case).
I'll keep this updated when I gather more. Their support page also gets updated too.
0 = Do not keep previous settings
1 = Keep previous settings
Note: This setting pertains to maintain existing settings in the package creation tab.
0 = Do not an entry to the Start menu
1 = Add an entry to the Start menu
u = unattended
s = silent
f = interactive
0 - Display a Yes / No option if reboot is needed
1 - Display pop-up and do reboot when UI level is f, u or s
3 - No pop-up and no reboot when UI level is f, u, or s
0 = Do not run LiveUpdate at the end of the install, which overrides the RUNLIVEUPDATE property
1 = Use the default behavior for running LiveUpdate
