SCCM 2012 : “Another Installation is already in Progress” when deploying Applications thru OSD deployment.

At one of my current customers, I have been stuck for two days now, that one or two randomly selected applications where failing If we looked in the ‘Status Messages’ and dig al little deeper , we saw in there that :

‘Another installation is already in progress.Complete that installation before proceeding with this install.’


Knowing this is a highly secured environment , my first guess would be policies. However I overruled this thinking strategy because during the OSD process , GPO’s aren’t applied …—> That is a fact , except for one scenario I already blogged about it as described here  ‘’ , but that was not the issue…

Back to the drawing board and digging deeper in the smstslog file … Suddenly when hitting the F8 button a popup arrived that I needed a reboot to complete the “Kaspersky Antimalware Client”  … WTF is that doing in my task sequence.

Apparently someone at the customer decided to set a policy at the Kaspersky management server , to Push / Install a Kaspersky client when he detects and scans the network for computers that did not had a Kaspersky mgmt. agent installed. That little process hijacked my Task sequence installation process and jumped in the middle to install that Kaspersky agent .

Case Closed …My advise – before troubleshooting Configmgr , just start asking questions who did changes on other parts of the environment Emoticon die tong uitsteekt

Hope it Helps ,
