Thank you for opening this issue, a team member will review it shortly. Until then, please do not interact with any users that claim to be from Sui support and do not click on any links!

[stefan-mysten]

@pandajc thanks for the report. I assume you have the binary from the v1.62.0 release?

[stefan-mysten]

@pandajc does it work with v1.61.2? or with older versions? Any more information you have will help us to figure out what happened.

[pandajc]

@pandajc thanks for the report. I assume you have the binary from the v1.62.0 release?

yes, I downloaded sui-devnet-v1.62.0-windows-x86_64.tgz from release page

[pandajc]

@pandajc does it work with v1.61.2? or with older versions? Any more information you have will help us to figure out what happened.

I have tried these versions, but no can work, all version printed 'Segmentation fault' at the end of console, I don't know is there any extra operation I should do for my windows11, rust and cargo are installed in advance.

sui-devnet-v1.62.0-windows-x86_64.tgz
sui-testnet-v1.61.2-windows-x86_64.tgz
sui-testnet-v1.52.1-windows-x86_64.tgz
sui-testnet-v1.39.1-windows-x86_64.tgz

I have given up using sui binary in win11 and I installed them in WSL2, it works well with WSL2 because it actually runs in ubuntu.

By the way, I remembered solana official document tells windows user must use WSL to develop Solana programs, I was wondering maybe some tools with rust is not totally compatible with windows system?

[stefan-mysten]

Thanks @pandajc , that helps a lot. Unfortunately, we had a hard time to replicate. I tried on Win 10 and Win 11, so something else must be going.

The 1.62.0 binary has an update where it compiles with higher amount of stack memory to avoid these kind of issues, so it's strange that it does not work. I'll ask a colleague that just got a fresh Windows machine to try it out and will get back to you.

[stefan-mysten]

@pandajc we were able to replicate on a Windows 11 machine and will try to debug tomorrow. I'll keep you posted.

@pandajc we managed to reproduce this issue and possibly fix it. It looks to me like it's a linking issue (or old libraries) and an installation of Microsoft MSVC build tools solved it. Here's exactly what we did and what I would suggest to do:

• we installed Rust using this script by copy pasting it in Git Bash: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh and followed the prompts to install visual studio tooling.

After this, it worked so I think some of the libraries / runtime sdks that get installed will fix this issue. You can either try to install Rust as above, or simply install Visual Studio Build Tools (https://visualstudio.microsoft.com/visual-cpp-build-tools/).

Let me know if you manage to get it running like this!

Thanks for your working, I checked again and I found there is an issue with my Visual Studio 2022, which was installed long time ago, the "Desktop Development with C++" in Work Loads was not selected, so I installed "Desktop Development with C++" with Visual Studio installer and I'm sure the MSVC , windows 11 SDK is included now.

After that I run curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh in Git Bash to install Rust again.

Then run RUST_LOG="off,sui_node=info" sui start --with-faucet --force-regenesis in git bash, failed again.

After that I realized I did not config environment variable for Visual Studio 2022, so I did a research to find what variable I should add, and I followed other developer's guide to config these vars:

VS170VCTOOLS
D:\devsoft\Microsoft Visual Studio\2022\Community\VC\Tools

WIN10KITS
C:\Program Files (x86)\Windows Kits\10

WINDOWS_SDK_VERSION
10.0.22621.0

add this into PATH
%VS170VCTOOLS%\MSVC\14.37.32822\bin\Hostx64\x64

INCLUDE
%VS170VCTOOLS%\MSVC\14.37.32822\include;%WIN10KITS%\Include\%WINDOWS_SDK_VERSION%\shared;%WIN10KITS%\Include\%WINDOWS_SDK_VERSION%\ucrt;%WIN10KITS%\Include\%WINDOWS_SDK_VERSION%\um;%WIN10KITS%\Include\%WINDOWS_SDK_VERSION%\winrt;

LIB
%VS170VCTOOLS%\MSVC\14.37.32822\lib\x64;%WIN10KITS%\Lib\%WINDOWS_SDK_VERSION%\ucrt\x64;%WIN10KITS%\Lib\%WINDOWS_SDK_VERSION%\um\x64

Reboot win11 system.

Run curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh again to install rust.

Run RUST_LOG="off,sui_node=info" sui start --with-faucet --force-regenesis, failed again.

Oh, sorry it did not work :(

I'll have to think, not sure how to debug this from afar.

[stefan-mysten]

Could you maybe try to check if you either have installed Build Tools for Visual Studio 2026 or if you could install it?

Could you maybe try to check if you either have installed Build Tools for Visual Studio 2026 or if you could install it?

Visual Studio Community 2022 17.7.5 installed (including MSVC v143 -VS 2022 C++ x64/86, windows 11 SDK 10.0.22621.0 and etc.), and Installer tells Visual Studio Community 2026 is available to download but I never install 2026.
