Fresh Install of Home Premium, missing PCI Serial Port Driver  

Computer: Dell OPTIPLEX 755
OS: Windows 7 Home Premium (x64)
Problem: Missing PCI Serial Port
Fixes tried:

AMD Radeon HD 2400 XT Graphics Driver Driver Details | Dell Australia (AMD Radeon HD 2400 XT Graphics Driver), complains that it is a multidisk installer and needs the last part to be inserted.

Intel G31/G33/Q33/Q35 Graphics Controller, v.6.14.10.4957, A05 Driver Details | Dell Australia (Intel G31/G33/Q33/Q35 Graphics Controller, v.6.14.10.4957, A05), complains that it is a multidisk installer and needs the last part to be inserted.

Intel Matrix Storage Manager (OS Pre-Install Driver Only), v.7.8.0.1012, A12 Driver Details | Dell Australia (Did not give a specific setup installer, just installed a bunch of files.)

Intel AMT HECI, v.3.2.20.1049 PV, A02 Driver Details | Dell Australia (Used this to fix another error, worked for that one. Did not work for this one.)

When ever I scan for hardware changes in devmgmt.msc, it attempts to install the PCI serial port but is never successful.

Properties of the PCI Serial Port in the unknown devices section of devmgmt.msc shows this:



The drivers for this device are not installed. (Code 28)

There is no driver selected for the device information set or element.


To find a driver for this device, click Update Driver.

Any and all help is appreciated, thanks!

After a lot of searching, I finally found the solution. I had to install the 3 .exe's below and it worked like a charm.
