Hi, guys !
A .Zap file is not an option -- I don't want to publish, I want to assign.
Anyway, there _is_ a solution, trust me ! There's a command line for iesetup. Take a look at the following article in M$ knowledge base: Q257249.
If you'd inserted it as custom action, the only last thing to do is to restart PC _after_ installation and get logged on. But you can use startup script in order not to get logged on.
Moreover, you won't need to bother with IEAK any longer.
It really works, lads.
As for repackage -- yes, dmoritz, you're damn right, M$ stuff is a hell of an undocumented merde, I gonna play with it no more.
Regards,
CB
