PCI Simple communications controller -Failed

CCleaner free v 4.16.4763. Windows 7 Enterprice 64 bit, HP COmpac 6200 Pro MT

I installed and ran the program.

I set it to save the settings and run when the PC starts.

I ran Cleaner (once) and Registry (twice).

Then I rebooted the PC.

When The system was in desktop there appeared a talk bubble down right in the tool bar telling that the system was installing a driver.

Then it told that installing "PCI Simple communications controller" failed.

This same message appeared in all the computers, which were tested.

Computers wer of the same make and model.

have you tried to restore the backup you hopefully did prior to running either of the registry cleans?

PCI Simple Communication Controller is either an internal modem or Intel Management Engine (what my money is on) that will need reinstalling.

I have fixed the problem in all of these computers.

The report was just report.

How many computers were there?
