win-acme/win-acme v1.9.4 on GitHub

This is a long overdue bug fix release, which fixes some major and minor issues.

If renewal fails for any reason, LEWS will now keep retrying until it succeeds, instead of pretending that it worked. This was a very serious and annoying issue reported many times by different users (#510, #475, #474, #460, #458, #448, #446 etc.)
New --verbose mode for debugging, allowing the default mode to become a lot less chatty. In general the user I/O has been optimized and made more consistent across different parts of the program.
Default web.config changed to prevent common handler and mime type issues (#490)
The intermittent "specified logon session does not exist" error should be fixed now (#371)
If the webroot of an IIS website changes it is now updated during the renewal process (#499)
It's now possible to renew manually created certificates using a script (#299).
Update Json.Net to fix intermittent "request payload did not parse as JSON" error (#508)
Better support for unattended use
Many more issues
