Downloaded 3.11.16.830 a couple of months ago and tried to use for the 1st time today.
Initially I got 'Can't load Kernel S_HC16_v106' error.

I found a link on this forum to a Kernel download which contained S_HC16_v106

However, now I get the following :

I have never had a problem loading to this car's ECU on previous versions.

I have now moved all my ECUEdit files into backup directory and re-downloaded the latest.
This doesn't even appear to come with any Kernels ??

I run ECUEdit Pro/Admin, so not sure if this makes any difference.
Any help appreciated Thanks

I am having the exact same situation with my new installation of Ecuedit 3.11.16.380 Pro on Windows 8. I can log, but not write. Any attempt to flash results in the following error:

I have the same installation/same version of ecuedit on Windows 7 (my old laptop that is to be retired) that works perfect. 3.11.16.830 on Windows 7 logs and writes perfectly.
So I assume it is an issue with windows 8 / ecuedit 3.11.16.830...

I have compared the installation on win7 vs win 8 and the kernel files reside in C:\Program Files (x86)\ecuEdit\Kernels on both installations. So kernels are present.
XmlDefs of my ECU (A4RN1000) is present in xmldefs folder.

How can I overcome this issue?
Please help.

Problem solved.
I was missing the admin key.
