HP SA automated uninstall

[TedTice]

I've tried various methods for an automated uninstall of the HP SA agent on Windows servers.  I'm unable to get a true unattended removal to work.  I've tried the following to no avail, any thoughts?  

START /WAIT CMD.EXE /c msiexec /q /x {D9ADF11F-7A67-4E70-BD89-F29DE876C982}

^that using the GUID from the uninstall registry hive, it spawns a window and requires two confirmations, 'y'

I've also tried this one in a couple forms:

start "Uninstall" /WAIT /SEPARATE cmd.exe /C "%SYSTEMDRIVE%\Program Files\Opsware\agent\pylibs\cog\uninstall\agent_uninstall.bat" --force

^that calls the msi uninstall in the same path. 

also tried:

set OPSW_DIR=%SystemDrive%\Program Files\Opsware

set AGENT_DIR=agent

set uninstall_msi=%ADIR%\pylibs\cog\uninstall\agent_uninstall_x64.msi

msiexec /qn /x "%uninstall_msi%" REMOVE_MSI_ONLY=1

Also tried deactivating the server from the HPSA console.  Same issue/error as before.  Output is from the msiexe using the uninstall QUID from the registry.  

START /WAIT CMD.EXE /c msiexec /q /x {D9ADF11F-7A67-4E70-BD89-F29DE876C982}

Spawned window:

Looking for Opsware agent to uninstall.

WARNING: This server's list of attached nodes could not be determined.
This is likely due to a network condition preventing this server from
contacting the Opsware core or because this server has not been
previously registered or is already deactivated.

Do you want to proceed with uninstalling the Opsware Agent? [y/n]:
