How to setup SD connect C4 for Mercedes BUS diagnosis

I want to diagnose a Mercedes-Benz BUS using Xentry 2015.12 but the program displays “License is incorrect”. Luckily, got help from DieTrih. Copy the solution and result for sharing. Hopefully, it helps others also.

Software ver.: Xentry 12/2015

Tool: SD connect C4


HWID: 6CCA1532A511

AppID: 253

LAN-ID: 08005BABA84E


my cars are working fine.

cars and trucks working ok, so i bet it’s working Xenry; but cannot do buses or other heavy equipment MB. I only have this problem with Buses –> “licence incorrect”.


in Xentry this Licence Error Message (sorry, screenshot is in German; i have translated it into English).


Fahrzeug: CC400.121



Lizenz ist fehlerhaft

(Vehicle type: CC400.121



License is incorrect)



The solution for me….


DAS License.0 Fix download on Mega


with DAS.Standalone for Xentry.OpenShell.XDOS and DAS.Xentry (2015.12)

DAS v7.7.0.1

Use it with old keys for DAS.

MB Bus and Bharatbenz are working.

Included: das32r2.exe (Usual file), das32r2_sl.exe (Standalone), lic.sli (Original file if needed).

Don`t look on the file size, just packed executable.


mustang’s review: (BIG THANLS)

I confirm that DieTrih solution works perfect.

I used windows xp and windows 7.

all in 32 bits.

xentry das versions from 2015.5 until 2016.12

everything is working fine… also in bus

Elsawin 5.3 Windows 7 32bit Installation with Success

Elsawin 5.3 installation with success! I have installed ElsaWin 5.3 on Windows 7 Ultimate (32-bit) yesterday with success. All works fine.
Elsawin 4.0 i was using no issue, it’s very cheap now:


Elsawin 5.2 i’ve ever used, works fine:

also from this site:


And now Elsawin 5.3 download from it’s official blog
This is how i installed:
– first make shure that you have full authorizations in Windows 7 (administrator)
– Then turn off the DEP (data execution prevention) function in windows 7 by : Run CMD as admin, run command – bcdedit.exe /set {current} nx AlwaysOff , and reboot.

Run ElsaWin 4.0 till 5.3 as admin with XP compatibility. DO NOT ADD a database till you finished update 5.3, and with all installations “Check” and install the German language. (this to avoid missing graphics files.) i have done a reboot after each update.

Then install any DB you have!!

If the 5.3 version does not accept the DB because it’s to old just take one of the Control#??.xml files open it in Notepad++(google to download) in the bottom line you see the file nr. () change the ??(nr.) to “53” , then save a copy as : control#53.xml and add to your DB and you can run the BD with success. (tested)

Also check if the languages you have “checked” in the Elsa installation are in the DB setup, if they are not in the DB setup it can be that the setup will be cancelled and no DB is installed or that just the DB is installed but not in all the languages you sellected in the Elsa installation.

Check also before installation if the DB is complete. there are a lot of DB on the net that are incomplete, some have no Graphics file, some have just 1 or 2 languages or other files missing.
If you have a known working database use it to compare it with your new database.

i have installed for now the DB VW and Audi.

– VW Database_04.2015 36,3 GB (installed this first because of the size, maybe more complete and is with commercial vehicles)
– VW_01.2016 21.5 GB
– Audi_02_2016 25,3 GB – BEFORE INSTALLING THIS AUDI DB !! open it in Windows Explorer and look for the file : and change the name to:
It’s just a Typo (error in the name). replace the “_” in “#”. if you do not you get an error during installation and you end without the graphics.

i also have these DB: Seat 01-2015 and Skoda 03-2012 , But i did not installed them because mine versions are far from complete and useless.

I hope that this will help you and will get you also a successful installation.
