Unattended install of 7.4MO

[KWalsh]

Hi guys,
I'm trying to install 7.4MO unattended via SCCM and I've used your very helpful guide as well as the MSI installers.
The Core program calls the driver program correctly as I can see evidence of it installing, but it eventually ends in error - 1603 gets returned to SCCM.
I've altered the two MSI switches to include verbose logging and from there I can see lines like these:

Property(S): NOT_REBOOTED_ERROR = A previous uninstall of DisplayLink Core Software is not yet complete. Please reboot your computer and run this setup file again to begin installation.

Property(S): TRUST_ERROR_MSG = The software package appears to have been modified. Installation aborted. Please contact your vendor for assistance.

Property(S): CHECKSAMEVERSIONERROR = [ProductName] [ProductVersion] is already installed on this computer. Installation complete.

Before I start I look in program files - no displaylink folder. In regedit I've searched through HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Uninstall\ for Displaylink and there are no results.

Any idea how I can troubleshoot this?
Thanks

Could you post the setupapi.log from c:\windows after this problem happens as it should contain information to let us know what the problem is.
