Does V2018.9 MB Star comes with HHT-WIN software?

This user manual is aimed to help newbies and those who has issues with MB Star diagnostic system – HHT-WIN.
HHT-WIN is Hand Held Tester comes with XODS disks used for Mercedes diagnostics.
In essence HHTWIN is a hi-tech version of the LED blink code readers.
Post 1996 OB2 models are fairly easy to read, however the early diagnostic system HHTWIN encompassed within the very latest Star system is more difficult to get grips with, so this is a trial sticky topic to address any issues encountered using the hhtwin system.
A list to read the manual brief:
HHT-WIN vs Xentry vs DAS
HHT-WIN supports modules
HHT-WIN software install
HHT-WIN error & solutio
HHT-WIN user reviews
In detail….
HHT-WIN vs Xentry vs DAS: software and car support
Xentry took me to DAS, and DAS switched over (automatically) to good old HHT-WIN, again. Guess my 16-year old SUV’s system is a bit ancient in the scheme of Mercedes-Benz technology.
From what I’ve seen:
All MB from late 80’s to 99 = HHT-WIN
All MB from 2001 to 2009 = DAS
All MB from 2010+ = Xentry
The year 2000 is a weird transition period — some MB made in 1999 but the model year is 2000 will be diagnosed from the 38-pin under the hood and thus use HHT-win. Other MB made in early 2000 and sold as a 2000 model will have the OBD port and the SDS will require the OBD cable to diagnosis….and will use DAS.
And then there are orphan cars, like some SLK models — some 2000-2001 SLK require the 38-pin.
I’ve even seen a 2000 E320 that had both 38-pin and OBD port — I could use either port to conduct a full diagnosis. That was funny.
HHT-WIN supports modules on Mercedes vehicles:
HHT-WIN should be able to read all Modules.
Having said that, for Model Years 1990 – 12/1993, the Roadster Soft Top Module has 30 possible fault codes associated with it.
Whereas for Model Years 1/1994 – 1996, the Roadster Soft Top Module has only 11 possible fault codes associated with it.
HHT-WIN software install:
IMPORTANT: HHT-WIN is updated to 09.2018 Mercedes software disk. Software released in 2017 and 2018 doesn’t come with HTT-WIN. But now, it comes again!
HHTWIN directly install on Windows 7 32 bit:
Disable UAC settings to “Never notify” -> Restart system if needed. It`s better to DISABLE idiotic Windows Defender too. Then, you could return UAC settings back.
First simply run HHT.exe, it will install HHT to C:\HHT, then start Xentry.OpenShell.XDOS.HHT.C4.exe/Xentry.OpenShell.XDOS.HHT.C3.exe … that`s all.
Some systems must be restarted at the end.
The problem with “–” version was fixed.
Delete C:\HHT directory and begin from the first step.
If you will update your Xentry.OpenShell.XDOS version … just apply the patch once again.
HHTWIN install on Windows 7 with XP mode:
HHT-WIN – 100% without installation issues:
HHT-WIN error & solution:
  1. HHT-WIN setup on Dell D630 install
Error: I got my SDS last week , initially I chose the external USB disc option but have now installed it on my recently acquired Dell 630. Everything installed well, however when I get to the point of using it and it automatically goes to use HHT(as my car is a 1993 model)it says”diagnostic connector is being initialised” however then it says”com port assigned! close other use!”
I took this to mean I had it on wrong COM port and sure enough I had it on COM 1 but have changed it to COM 2 both on the machine XP and on the virtual XP machine ( I am using the RS232 connector to the 38 pin diagnostic connector) but it said the same thing again.
Solution: go to the windows system menu in control panel and under the harware section look at the com port assignmennts and make sure the com port you designated isn’t already assigned to something else.
also, does the dell630 have a dedicated RS232 com port or are you using a usb/pcmcia/cardbus to RS232 converter.
  1. HHTwin resets the switches:
Error: How do I reset the switches with HHTwin? Or do I need a different software? My MUX is C3.


Solution: you can’t reset the switches. you can clear error codes, but the switch state is what it is. DAS is telling you what the switch state is. Or at least what it thinks the switch state is.
you’ll need to examine the switches and see if either they are misadjusted, not connected, or not functioning.
HHT-WIN review from real users:
Review 1: so far the SD Connect C4 & HHT has been informative. erased RST codes, top works, going through other functions found some neat ones. Turn on/off headlights, taillights, turn the electric fans onto each of the 4 speeds etc.
Review 2: On my new 2015 GMC Denali pickup, from the dash menu I can change between F and C for outside temp and coolant temp and transmission temp, and between MPH and KPH on the spedo, and between PSI and BAR on the oil pressure. I think I can also change the tire pressure readout between PSI and either BAR or KPascals. And I can even change the shape and location of the various gauges. Spedo and tach stay in the same place, but can change shape and display for oil pressure, transmission temp, voltmeter, coolant temp.
Review 3: I changed F to C with HHTwin. I also activated the rollbar. Kind of underwhelming.
Review 4: I did a short test today again and took pics this time
first pic after short test (F)
pic 2 LH1 (F)
pic 3 says LH1 and LH2 did not answer, but no fault on LH2(pic2)
pic 4 fault memory current faults
pic 5 and 6 stored faults










Review 5: HHT-WIN successfully read the RST (RV) Module for my 1995 SL500.

WIS error “No write access for installation folders”

When I started installation of MB Star diagnostic WIS standalone 01/2012 on DAS 03/2012 (clean install) on Windows Xp Pro ENG with 1G virtual drive. i did standalone key first, and used 1st DVD and used SDSwitch.
i got the error message “no write access for the specified installation folders ! ”


First, share some tips/ solutions i found on forums:

  1. Extract all the images in a folder for each dvd

Or use the virtual drive and mount the 2 images

Use pwr iso Kolo


  1. First install WIS standalone

As a part of MB SD Connect C4 DAS x 2012

Then mod d2ksetup


  1. Un-Install ANYTHING > Use the CleanEWAInstallation.vbs> Reboot > DELETE any Folders witch they remain > Re-Install again!

Good luck



Then i found the problem is “Information at 15:36:43 : Executing in CMD: cacls C:\Programme\ewa /T /E /G U|_ytkownicy:F


WIS installer did not recognize diacritics – should be “Użytkownicy” not “U|_ytkownicy”


So I changed name “Użytkownicy” to other word without diacritics – for example to “Users” or “Uzytkownicy”. To solve it, ran compmgmt.msc and went to “Users and local groups” ->”Groups” and rename “Użytkownicy”.


Finally SOLVED!


It is said that it’s possible to install standalone WIS on any language version of WINXP.
