No, it's the Windows build. Note however that it's a link to a webpage from which you can download it, do not savelinkas directly  open the link in your browser then click the Download button.
Or download it from https://download.mersenne.ca/YAFU if you prefer.

It's no better for me. Same crash (after startup) and session.log is still empty.

Btw, just like last time (post 175 in this thread) I am able to run yafu 2.10 on my Windows 7 x64 computer without any problems.
Code:

Per your other post I installed Microsoft Visual C++ 20152022 Redistributable (x64) 14.32.31332 both x64 and x86 versions but made no difference, same crash. I don't see much hardware feature difference between your Xeon E52687W and my i73930K.

I'm not sure if the windbg (windows debugger) can help track down what the illegal instruction is, but it may be worth a shot. You can install it by downloading the Windows SDK for Win 10
Windows SDK  With WinDbg Download the Windows SDK (it will say for Windows 10, but the installation page says it supports Windows 7 SP1). Then, to just get the debugger, the instructions say: Code:
In the SDK installation wizard, select Debugging Tools for Windows, and deselect all other components.

I reuploaded yafux64gc.exe.
This time I did a complete rebuild of the entire dependency chain starting with mpir3.0.0 (core2), then ecm7.0.4, ytools, ysieve, and yafu. In all MSVC projects I set the "enable enhanced instruction set" option in the code generation settings tab to "No Enhanced Instructions (/arch/IA32)". Although I don't know if this does anything because I see the message: "1>cl : command line warning D9002: ignoring unknown option '/arch:IA32'" scroll by when compiling. weird. Thanks for testing!

Sweet! Good to see progress.
Actually I realized now that I didn't update the msieve dependency, so maybe that will take care of the error you're seeing now. Might not be able to get that updated until tomorrow.
