My domain is: mickwebsite.com
I ran this command: certbot-beta-installer-win32.exe
It produced this output: Created a folder c:\Certbot
My web server is: Microsoft Internet Information Server version 10 [IIS 10]
The operating system my web server runs on is: Windows 10
My hosting provider, if applicable, is: Myself and my home computer, my ISP is Rogers Communications Inc, a Canadian communications and media company
I can login to a root shell on my machine: Yes
I'm using a control panel to manage my site ): Yes, Internet Information Services Manager [iismngr]
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): I cannot find certbot.exe on my computer, not in c:\Certbot or either of the the ProgramFiles folders. I Cannot change to directory C:\Program Files (x86)\Certbot\bin\
Notes:
While I was preparing this I found the certbot.pdf I have not studied it yet.
In c:\Certbot:
the lib folder is empty,
the log folder contains files dated March 3 thru March 10. I "do not have permission to open this file". I signed on to the administrator account and opened the file letsencrypt.log and discovered the home for certbot is
C:\Program Files (x86)\Certbot\bin\certbot.exe
It is a hidden file that I cannot see even as administrator. I do not have a clear understanding of Windows permissions for files and folders.
In the folder c:\Certbot\renewal\ I see mickwebsite.com.conf and its content, among other files.
I'll await further instructions/information before proceeding
