Here is theresolution of Mercedes MB Star diagnosisSD Connect C42016.05 Xentry SDconnect Toolkit incorrect parameter fault.   Problem:
I have installed05.2016 XDOSon Win7 32bit, everything were ok during installation and after, but when i tried to connect my sd connect via Lan i got message like on photo that parameters are incorrect. I have reinstalled XDOS again and got the same message, then i tried to install on 64-bit system and this time everything works. What could be the reason?   Customer solution: Change your computer name with word A - Z , i think your computer name with Russian Word, after change computer name, reboot PC.. All will be fine..     Result: It worked. 2016.05 Xentry now runs no problem. Thank you a lot!!! http://blog.mbstartool.com/2016/07/26/sdconnect-toolkit-incorrect-parameter-fault-599/
