Most likely, your CPU doesn't support AVX2 and/or FMA. The project files are set to compile with AVX2 and FMA support and you need to disable it in build settings.

Xcode: Set "Enable Additional Vector Extensions" to your supported level. Remove -mfma and -mno-fma4 from "Other C Flags".

Visual Studio: Set "Enable Enhanced Instruction Set" under code generation to your supported level. Remove __FMA__ from the preprocessor definitions.
