OptiPlex 790 running Windows XP x86
I used an Acronis image of an OptiPlex 755 to build a HDD for the 790 using Universal Restore with known good WinPE drivers. Known good driver packs (Software, Chipset, Intel AMT, USB3, PCIE, NIC, Audio and Video) all installed correctly, in that order except the Intel AMT. I was getting an error during install: The setup program failed to install one or more device drivers. In Device Manager one item was flagged: PCI Simple Communications Controller. In the properties it indicated the driver was heci.sys. Checking another 790 revealed this should be Intel(R) Management Engine Interface. The HECI driver would not install manually, returning the error, "The name is already in use as either a service name or a service display name."
SOLUTION (the one that worked for me): Delete the HECI key under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and Restart (the usual REGEDIT cautions apply). Upon login the system will find new hardware. Point at the HECI in the MEI folder from the Intel AMT driver pack. The device then install properly.
I got the clue that led to the solution here: http://support.microsoft.com/Default.aspx?kbid=823771
The post is the answer
Thank You! Thank You! This was definetly the solution I was looking for. With out nuking that reg entry they refused to install. For added clarity the drivers are found in the AMT-7 At the time of this posting R298379\Drivers\MEI
The newer versions of the drivers work with all windows.

Tested these drivers with this situation; does not work. The HECI driver installer reports that "This computer does not meet the minimum requirements for installing the software." Sorry.
Recently installed Windows7-64bit on my Optiplex 755 and had two outstanding device manager issues: 1) pci simple communications controller and 2) pci serial port. Ran all 3 of the above installs (which also installed AMT) and both device manager issues were resolved.
