Fixed
- Step 7 (build) fails with
unknown type name '__m512i'/'__m256i'(#8). LLVM (clang-cl) 18 and older can't compile the game's AVX2 / AVX-512 code paths. The launcher now checks the LLVM version: an older one shows TOO OLD under the build tools with an Update button, which installs the current LLVM over it with winget. Then press Build; only the last step reruns.
The launcher updates itself (Update now), or download inFamous2Recomp-v0.1.15-windows.zip / inFamous2Launcher.exe below.
