Builder version

HookshotBuilder zip downloaded on 07/11/2026 (HookshotBuilder.exe dated 06/11/2026 19:25). Exact release name not known.

How you built

Hookshot Builder app (Windows)

Game files given to it

A .nup

The error

The build finishes successfully ("Your game is ready", 48 min). The problem is at launch: hookshot.exe closes right after starting, no window appears.

CPU: Intel Xeon E5-2667 v2 (Ivy Bridge: has AVX, no AVX2/BMI2/FMA3)
GPU: AMD RX 6600
RAM: 32 GB
OS: Windows

hookshot_log.txt:
[hos host] boot: image 96 MB at 0x80000000, 9809 MB of memory for the game
[hos host] CRASH: exception 0xc000001d (read 0, guest 0xfffff00000000000) at hookshot.exe+0x190dcf07

0xc000001d is STATUS_ILLEGAL_INSTRUCTION, so I suspect the generated code needs AVX2 (or a similar Haswell-era instruction). Is there, or could there be, a baseline/no-AVX2 option for pre-Haswell CPUs?

Visual Studio or Build Tools version, and Windows SDK version

Visual Studio Community 2026 18.11.3, "Desktop development with C++" workload (MSVC and Windows SDK from that workload; exact versions not checked). The build itself finishes fine.

Operating system and free space on the output drive

Windows 11 <versão do winver>, GB free on D:

Before you send it

I'm on the newest release, or it still fails on it.
I searched the open issues for this error.
I'm not attaching game files or anything built from them.

Found it: the game was always built for CPUs with AVX2 (x86-64-v3), and the Xeon E5-2667 v2 doesn't have AVX2, so it stopped at the first such instruction (0xc000001d). Since the game is built on your own PC, the builder now checks the CPU and builds for x86-64-v2 when AVX2 is missing (a little slower, but it runs). This is in the next release; rebuild with it and it should start. I'll ping here when it's out.

Fixed in the new release: https://github.com/NotRexed/Hookshot/releases/tag/no-visual-studio (rebuild your game folder with its HookshotBuilder.zip; it no longer needs Visual Studio). If it still happens with it, please reopen with your hookshot_log.txt.

Thanks for the quick fix! I rebuilt with the no-visual-studio release and the game now launches on my Xeon E5-2667 v2 (no AVX2). It still crashes, but later: the intro plays fine, and when the game title logo appears, the screen goes black, then the game freezes and closes. Every time, same spot, also at 50% resolution. The same .nup crashes at the same spot in the Lichii emulator too. GPU: AMD Radeon RX 6600 (8 GB), driver <Adrenalin version> CPU: Intel Xeon E5-2667 v2, RAM: 32 GB OS: Windows 11 <winver> Builder: no-visual-studio release hookshot_log.txt attached (taken right after the crash). Last lines: <paste the last 10-15 lines> This looks like #150 (device lost). Should I continue there, or reopen this one?
