Also, have you checked the execmgr.log log file for an error code?

Hello

I am using SCCM 2012 R2 in my environment recently. I am able to install SCEP to most of my computers, but there are around 150 computers that are facing difficulty in installing SCEP because of old incompatible antivirus (Password Protected). The protected password cannot be removed silently and the old antivirus server is already down. I have made a script which will uninstall old antivirus and installs SCEP, and it is running perfectly when installed locally. When i package it and deploy to my collection, it is not installed on my clients. When i monitor my deployment the package appears in the error tab. I also searched some resources in the internet but of no use. Pls help

Thanks

Ashok

What product is the old antivirus?

All Configmgr is doing is running your script via command line using the local system account.

Download pstools

run psexec -i -s cmd.exe from a command line.

This will open another window, check it's open with the system account by typing whoami.

Then run your script from that command line window and see why it fails.
