Turns out that you can disable AVX support on Windows using a tool for modifying your boot configuration (Boot Configuration Data, BCD). To make sure that AVX is enabled, do the following:
- Open your Windows Power Shell in Admin mode
- In the command line type: bcdedit /set xsavedisable 0 (do NOT set this value to a number other than zero!). You should get feedback that the operation was successfully completed.
- Exit Power Shell, reboot your PC and see if the error message persists when you start D2R
Normally, this should not be an issue, but it’s worth a try.
