Netware 6.5, Zen 6.5 and client 4.9 SP1a & SP2

I build an application useing snapshot. Test the app, everything works
fine. The powers that be want it rolled out off hours. I set it up to
roll out to the workstation object using lights out. Next morning the app
is there and life is good.

Then, 24 hours later the application uninstalls, I did not remove anything
from C1 or change anything in the application object. Any ideas why the
application would uninstall?
