I'm always have the same problems:

Package an installation with also current user registry settings. then
ZCM > install network msi > install once per device

Then the first user get's the user registries correct, but the second user that logon doesn't get the user registries.

I'm always trying to do ALLUSERS=2 (for windows xp sp3), and hoping everything is going for all users, but think that's not everything i have todo to get it perfect.

What is the best way to solve this kind of problems?
