Action Configure_HostService, location:
C:\Windows\Installer\MSI53A4.tmp, command: -config=TaskManagement -dir="C:\Program Files\Altiris\TaskManagement\"
In this particular environment, the diagnostics msi was not installed (causing that aexconfig failed to run when the MSI called configuration step)
Make sure that "altiris_diagnostics_x_x_x64.msi" for the version that you are trying to install or repair is installed and configured.
