I'm attempting to uninstall Zenworks Adaptive Agent 10.3 on a Windows 7 x64 system with the following switches:
C:\Program files (x86)\novell\zenworks\bin\zenworksuninstall.exe -c -d -q -u administrator -p xxxxx

I'm running the uninstall as the Local System account. The agent fails to uninstall and the following message appears in the novell-zenworks-uninstall.log:

The same command works fine when I run it with my domain account.
What is the proper way to uninstall the Agent when using a local account?
