We have tested it on Windows 10 pro and Windows server 2019 and it is working fine. (Also tried building the local pywinpty but unable to build it.) ref link for winPty https://github.com/rprichard/winpty#:~:text=winpty%20is%20a%20Windows%20software,in%20a%20Cygwin%2FMSYS%20pty.Does winpty.exe run, if executed from the command line instead of pgAdmin? If not, does dependency walker show any missing libraries that are required?Not found the winpty.exe in site packages, but as per the winpty documents "winpty-agent.exe" will start the process with a new, hidden console window. It is not showing any error while installing the package. I tried to use it outside the pgAdmin but still facing the same error "Exception in import winpty DLL load failed while importing winpty: The specified procedure could not be found."(created a separate python environment for this)1. if try to run winpty-agent.exe from the command line, it shows the user entered inputs on the same terminal, not showing any errors.2. I found winpty.exe in the other installed app (Git command line: C:\Program Files (x86)\Git\usr\bin) if try to run it through the command line not getting any error, it is showing user entered inputs on the same terminal. (It is not related to pgAdmin but just tried to check winpty.exe throwing any error or not)Hmmm, that sounds oddly similar to an issue I had with Kerberos on Windows when I was mucking around with that. I can't remember the exact details, but as a test, does the problem go away if winpty.dll is copied into the Windows system32 directory?Tried it but still facing the same issue.
OK, I had a fiddle around, and see the same thing. I can't do a simple import of winpty. On 2019 it's fine. I tried various tricks that I've used in the past to make sure libraries are found etc.
Could this be because it's trying to use the conpty interface in Windows 10 and above?
If we can't get this to work tomorrow, I think it's fine to simply hide the menu options and button if the server detects it's running on an unsupported version of Windows. Of course, this should be documented. We also need to make sure we know *exactly* what versions it does and does not work on.
