Try to distribute PDF24 V2.8.4 with the command line parameter /verysilent as an update (V2.8.1 is already installed) to our Windows XP SP3 workstations.
We are using System Center Essentials for distributing: PDF24 is installed exactly the same way as Windows Security Updates are installed with the option "install updates and shutdown" from the start button.
But the installation hangs forever, and Windows doesn't shutdown. We have now discovered that when a user with local admin rights is logged on before, the PDF24 installation finishes successful and Windows shut down.
We never had this problem with any other SW- or security update installation, because the installation starts after the user has logged of.
Thank you in advance for any advice!
