Manually installed ziswin not starting

Hi all: Testing a new reimaging method in light of issues I
have with newer zfdagent. From what I have read ziswin can
be installed manually so that the full zfdagent is not
needed to restore image-safe data. However, my testing has
shown that ziswin will not kick off following a reboot like
it should (assuming the just imaged flag is set).

My manual install consisted of:

ziswinexe -> c:\windows\system32
ziswinr.dll -> c:\windows\system32\nls\english

Then run ziswin -install to set registry key. Supposedly
this should result in ziswin kicking off at every startup
and if the "just reimaged" flag is set restore the
image-safe data.

Can you help me out? Why will ziswin not start? Thanks,
Chris.
