Hi,
If you're having this issue, I suggest giving the regular Windows 10 installer a try by creating Windows 10 installation media (generic non-Enterprise edition) onto a USB key and running the setup file in Windows 8.1 Enterprise.
When you run the setup file from the USB key, it will recognize your enterprise version and offer to upgrade to Windows 10 Enterprise.
Also, currently in Microsoft Q&A we only support English, you may reply us in English and we can continue this thread discussing.
Hope above information can help you.
