Software Deployment

I use System Center Configuration Manager to deploy software etc on Vista clients 32bit
I need to deploy at printer driver for a HP Laser Printer in this case a LaserJet P1005
I always do the same thing with other drivers just by using PNPUTIL
Like this pnputil.exe -i -a hpljp1005.inf
but this is apparently not enough !!
On my test computer with at test user (has no priviledges to install)
The package installs fine and the printer works but the same dialog keeps comming up
Windows is finishings the installation af the software

Finish the installation or
Ask later

What can be the problem?

regards

Sweede
