I've tried v7.7.2.0p1-Beta, v7.7.2.0p1-Beta and v0.0.24.0 - none of these 3 contain a sshd.exe that would work on 32-bit windows 7: upon executing windows just barks that it's not a windows 32 executable file.

@Drugoy, Could you double check your machine is 32-bits machine? I validated the OpenSSH-Win32.zip is 32 bits. I tested on 32-bits win8 machine

At least for Windows 10 64-bit, I was able to run the OpenSSH 32-bit just fine. This is what I would expect (most 32-bit applications run perfectly fine on a 64-bit system if the SysWoW64 subsystem is installed). I do not have a 32-bit Windows 7 machine to test on though. The executable look fine to me.

@bingbing8 yes, it is 32-bit. Even if it wasn't - I'd be able to execute 32-bit binary anyways. Maybe it is just incomatible with Windows 7.

@Drugoy, I tried OpenSSH-Win32.zip on x86 win7 sp1 machine, the binaries work fine. Can you check if the package you downloaded are 32 bits?

NoMoreFood commented 6 years ago

It may also be worthwhile to temporarily disable your antivirus solution to see if the behavior changes or clearing the internet-downloaded flag that might be set on them (using an NTFS stream). You can do that by right-clicking on all files, go to properties, and chose the option to 'unblock'.

@Drugoy, you can check if the package you downloaded is 32 bits or 64 bits by dumpbin.exe shipped with visual studio:

"c:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\dumpbin.exe"
d:\test\sshdtest\sshd.exe /headers
