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..
