VMware Virtual Machine does not sysprep properly

Finding information from this log:

c:\windows\temp\guestcust.log i discovered the following errors:

Rpci: Sending request='deployPkg.update.state 4 101 C:\WINDOWS\TEMP\vmware-imc\guestcust.log@The system cannot find the file specified.
'

Rpci: Sent request='deployPkg.update.state 4 101 C:\WINDOWS\TEMP\vmware-imc\guestcust.log@The system cannot find the file specified.
', reply='', len=0, status=1

...which was stopping me being able to 'Deploy Virtual Machine from Template'.

To resolve this I uninstalled the Altiris Endpoint client.
