Scripting

I've done like this:

Commandline:

%windir%\system32\cmd.exe /c cscript.exe WaitForInstallation-W7-NewAgent.vbs

Script: WaitForInstallation-W7-NewAgent.vbs

Dim oShell
Set oShell = CreateObject("Wscript.Shell")

wscript.echo "Waiting for KACE to start the software installation..."
WaitForProcessToClose "runkbot.exe"
wscript.sleep(10000)
WaitForProcessToClose "runkbot.exe"
dim Scripttime, i, RoundTime, RoundCount
Scripttime = 180
RoundCount = 0

I hope it helps :)

Not sure i completely understand the question but you can set up the app installation as a post install task. If you already have it set up in the K1000 as a a managed install you can import that into the K2000 Asa a post install task. 

Check it out here.

A post install task would defintely work.

Otherwise, the K1000 doesn't need to the system to be on the domain to deploy an application, just needs the agent is installed.  The system would need to be able to check into the K1000, after that, deploy your application as normal.

The one caveat to that would be if the application needed admin credentials, you would have to use local administrator credentials until it joined the domain.
