My machines on the network are running ZFDAgent 6.5 on Windows XPPsp2
and I would like to upgrade to 7sp1.
I can push down the .msi and install the new agent without it rebooting
the users workstation, however it has of-course killed the 6.5 agent so
the NAL distributed icons are nolonger available until the user
restarts their PC.

Does anyone have a clever way to install it without killing NAL and
without requiring a reboot. Or better yet, can it be installed on
logout (I had a brief shot with the Group Policy Logoff scripts, but it
looks like NAL is already closed by then)...
