    Windows 7 x64 drivers for Optiplex 755


      I installed Windows 7 x64 on my Dell Optiplex 755 and need the following Intel Drivers AMT HECI & AMT SOL/LMS


      This system is 1.5 yrs old with a extended warranty and Dell will not support this as they have advised that they will not accept windows 7 on these units?

      They advised to try Vista x64 drivers but the system will not accept.


      I can't beleive that Dell have no interest in supporting this and hope that someone can assist>

          They do care about us, stephenscott (sort of)! Thanks to finding your note through searching for my own needs, I found you and hopefully the answer!


          There was this post at http://en.community.dell.com/forums/t/19299853.aspx?c=us&l=en&cs=&s=gen that prompted the investigation.

          I have an Optiplex 755 Core 2 Duo E8400 3GHz on which I have installed Windows 7 Professional from scratch (formatted the hard drives completely). I have installed 64-bit, but this will work for both of us.


          1. Go to the Dell website, http://support.dell.com/
          2. Click on "Drivers and Downloads" button at top.
          3. Search for R194010 (and R194011 after that) using the search box in the upper right of the Dell support page.
          4. Click on Intel AMT HECI, v., A01 (like the first in the list of results, for R194010; Intel AMT SOL/ LMS, v., A01 for R194011).


          Take a look at the "Compatibility" section - there we are, OptiPlex 755! And yes, they are for Vista, but they work for Windows 7, too - at least they have been reported to have worked for the posters at the Dell forum referenced above. (I am verifying that the Vista drivers work for those of us in Windows 7 land - the posters at the Dell Community forum seemed to be indicating so.)


          I'm going to go try things out. I will return with my report.

            IntelHECI.logIntelMESOL.logThanks, I have tried both of these with the following results. These were both downloaded from the Dell site for my Optiplex755 setting the OS as Vista x64 R194010 - on install I get "operating system not supported" R194011 - almost installs but fails when the intel unzip stops at "difxapi.dll" I am installing Windows 7 Home Premium as a complete fresh install.

              My Optiplex 755 is a Core 2 Duo E6550 2.33 GHz My Control Panel Conflicts within Other Devices PCI Serial Port PCI Simple Communications Controller USB Transceiver I have the 2 Log files on the install as well

              • 4. Re: Updated info and error logs

                My machine is an Optiplex 755 is a Core 2 Duo E8400 3.0 GHz - I have installed Windows 7 Professional


                My BIOS before my work yesterday was at A10. I updated to the A15 BIOS but still I have the conflict with the two PCI devices, as you also list here.

                Sorry for not getting back on R194010 and R194011... I kept poking at all the info provided at the Dell forum and by the end of the workday I was relizing it's not a solution - I have inquiry in there to see what experience people had because there are people saying it "worked!" but when I looked those patches up they are even older than my A10 patch level! So, sorry you headed down that path with my misdirection... hope your machine is OK after the exercise.


                Be forewarned... I searched via Google and came up with one of those "driver" websites that proclaims they have drivers for "everything"... well they had an older driver yet! I'll keep poking around and keep in touch here. You having the Home Premium version shouldn't make a difference with the BIOS, so I am hoping if I find something it will benefit both of us - I'll search with that in mind. -- The hunt continues!!!

                • 5. Re: Windows 7 x64 drivers for Optiplex 755

                  OK, here we go...

                       I have installed the drivers (Vista x64 drivers in R194010 and R194011) just fine and I have cleared the "PCI" devices out of the "Other devices" list with this effort. Here's the rub... you might not be able to accomplish this with your Home Premium installation of Windows 7 (I have Windows 7 Professional installed) ... because that is the difference between the Win 7 flavors... the XP-compatibility component. Notice at the Microsoft Windows 7 edition comparison site (http://www.microsoft.com/windows/windows-7/compare/default.aspx) that one of the features that Home Premium lacks over Pro and Ultimate is "Windows XP Mode". For those of us with Pro or Ultimate, that means that we can install "old", pre-Windows 7 software and, thus, run older installers.

                       Now, I haven't had an opportunity to test this yet, so I am hoping you will want to have a go at trying this out... and hopefully it will work, somehow. I had to run the installations for the drivers after I hand expanded them to their respective folders.


                  Notice at http://tinyurl.com/yajhp5v (I made this a "tiny URL" because the other was so huge - I have included it below, just in case - note 1) that it says that the 755 has been "Tested for Windows 7 Functionality" but that we are to "see note below" - which says "If a piece of hardware does not install correctly, you may need to install Vista drivers." (This is what you found out in your attempt.) It also refers us, with a link, to an article to teach us how to install the Vista drivers - but that is not very helpful in that vein.


                  So here is what to try (and I have done this on my own machine to the point of success):


                  Download the Drivers:

                  1. Go to OptiPlex 755 Drivers & Downloads page: Navigate to http://support.dell.com/ - Click "Drivers & Downloads" - Provide your Service Tag number or select a model (either way is fine).
                  2. Select either Vista 32-bit or 64-bit Operating System (for us, 64-bit) and "Chipset" in the "Category" drop-down list.
                  3. Download the AMT HECI driver (R194010 - "PCI Simple Communications Controller") and the AMT SOL/LMS driver (R194011 - "PCI Serial Port"). (You can also download the "Chipset Software Installation Utility" if you want but it is not required. That installation behaved, unlike these other two.)
                  4. The files have been downloaded as R194010.exe and R194011.exe Run both of those executables: They are auto-extracting executables and will ask you where you want to extract the files to. These directories will not be removed upon an unsuccessful installation attempt. (Maybe you still have them there.)


                  Install the drivers as administrator:

                  1. Run the installations by going to the respective directory (R194010 or R194011) and right-click on the respective setup.exe file.
                  2. Select "Run as administrator". This attempt will fail and you will see an error dialog box, but once you click OK there, Windows 7 will supply another dialog box labelled "Program Compatibility Assistant". Click on "Reinstall using recommended settings." (This is the standard compatibility response while installing that "older" software - even Vista oriented software. This is also where I think you might get stopped, Stephen.)
                  3. Everything proceeds just fine from there and the driver is installed. This is the section you will repeat for each driver.


                  Confirm that this has solved the problem:

                  • Go to Computer Properties | Device Manager. Note that the "Other devices" list is gone and that "Intel(R) Active Management Technology - SOL (COM4)" appears under "Ports (COM & LPT)". (This is Intel device 29B7, the "PCI Serial Port" that used to be under "Other devices".)

                  R194011 - Intel AMT SOL/LMS - PCI Simple Commincation Controller - VEN_8086 DEV_29B4

                  (Found the VEN and DEV info under each device's Details tab, selecting Hardward Ids in the drop-down. I then traced them to Intel using the database search at http://pcidatabase.com/ )

                    Thanks these suggestions worked ! I now have No conflicts showing in Device Manager. THANKS! The only issue remaining was when I installed the R194011 I received the following message: Intel Active Management Technology - Disabled To Enable/Disable contact your authorized system admiinistrator For more information click here (which takes you to the Intel website). This windows also pops up on startup. I am currently the only user and am setup as administrator? What am I missing?  Soo Close !

                    • 7. Re: Windows 7 x64 drivers for Optiplex 755

                      I had the same problem, and was able to resolve it.  I am using Windows 7 Home Premium x86 ( 32 bit ), but this should work for 64 bit as well.


                      Download both Intel Drivers from Dell (R194010 and R194011).

                      Go into the folder where they were downloaded.

                      Right click the first file (R194010.EXE), choose properties.

                      Go to the Compatibility Tab and click "Run this program in compatability mode for:" and choose Windows Vista SP 2

                      Do the same for the second file (R194011.EXE) to set it in compatability mode also.

                      Run the first one and follow all the on screen steps.

                      Run the second one and follow all the on screen steps.


                      Then you will get the "To Enable/Disable contact your authorized system admiinistrator" message.  Now I believe that you can go into the BIOS when you turn on your pc and enable the Intel AMT, but since that is more of a business feature and you have Home Premium you almost certainly do not need AMT.  So to disable the message do the following:


                      Click the Start Button Orb.

                      In the Search box type "msconfig" without quotes and press enter.

                      When the System Configuration comes up go to the Startup tab.

                      Uncheck the box for "atchk   Intel Corporation" and click OK.

                      Restart your computer when prompted.
