Because I don't see the point of creating an account in the repo for the sake of this:well.. that means I can't check for AVX in the installer unless people are on win 10 or later. Not sure how useful it even is then, considering old hardware where this is important is much more likely to run Win 7 or 8.
In #1970 you write "I don't know how that can be done from NSIS which is restricted to using Windows API calls. I know how to do it in C(++) but not NSIS scripting."
Wouldn't Nsis CPUFeatures plug-in solve the problem?
