Dell Driver Update over SCCM

Hi all,

I installed the Dell Command Integration Suite to our SCCM console and also deployed the Openmanage agent on a test notebook. Now the notebook reports to the sccm which drivers are needed and I published and downloaded this drivers and also deployed them to the notebook. But they won't install. I only can see that the notebook is still in unknown state when checking the deployment status in SCCM. Did I miss anything?
