I was trying to update the Dell ControlPoint System Manager update from A15 to A16 on my Dell Latitude E6410 laptop today via a package created in SCCM.  However, in trying to use the silent installation command:

msiexec.exe /i dellsysmgr.msi REBOOT=ReallySuppress /qn /l*v %TEMP%\DellSysMgr.log

The installation continued to fail.  When running it non-silently I’m getting the following prompt:

—————————

Question

This will update the System Manager software present on your system. Note: This version will no longer integrate into the Dell ControlPoint launcher. Continue?
—————————
Yes   No

So far I’ve tried the following command line Properties without success based on an .MST capture to compare the MST to the original MSI file:

ISCHECKFORPRODUCTUPDATES=0

UPGRADE_REMOVE_DCPFRMWRK=1

ISACTIONPROP1={4DEF2722-7EB8-4C5F-8F0A-0295A310002A}

SYSCAP.LLP=1 or 0

SYSCAP.PORTABLE=1 or 0

LAUNCHREADME=1 or 0

InstalledSysMgrVersion=1.4.00001

Eventually I just gave up and used the old standby approach of uninstalling the old version before installing the new version with the following command line:

MsiExec.exe /X{4DEF2722-7EB8-4C5F-8F0A-0295A310002A} /QN REBOOT=ReallySuppress

Anyone else have a more elegant solution to this problem?
