[JSL]

Thanks @JSL for the feedback. noted. but it is weird. i have tried install in win 10 x86 32bit dell e5510, sometimes connected to internet to update addons and it is no problem.
i don't use it anymore because i just want to feel the win10. my win7 so far no problemo.

I have 64bit Windows 10 running on Toughbook CF-19 mk3, but I suspect the issue is not the 32/64 bit or the hardware. How long did you have it connected to the internet and did you have Xentry or standalone DAS running at the time?

After installing and applying the fixes etc. I was able to launch Xentry without issues and I also configured the network to allow communication with SDConnect C4 (I did not try plugging it into the car and running diagnostics). Rebooted the computer and did it all again to make sure everything was working. It was. Then maybe 30mins later Xentry would not start anymore but would show me the "No access authorization code" error.

I should note this exact same thing happened with Win7 (32bit) and the Xentry (also version 2017.12) installation that was on the computer when it arrived from China.
