1. Navigate to the folder path where you installed win-acme, then run the wacs.exe file to open the command line interface.
2. The client should ask what command you want to run. Type N and then press "Enter" to start creating a new certificate with default settings.
3. You should now be presented with a list of IIS websites. Next to each website is a number. Find the IIS site you want to secure and the number associated with it. Type the number and press "Enter".
- Note that if you press enter without typing a number it will attempt to issue an SSL certificate for every IIS website.
4. It will now ask what bindings within the IIS site you want to secure. If you want to secure all bindings, type A and then press "Enter".
- If you do not want to secure all bindings within the IIS site, you can type P instead, then enter the search pattern for finding hostnames that match the inputted search.
5. You will now be asked which binding should be used for the subject name for the certificate. Choose one of the bindings by typing the number associated with the binding displayed and then press "Enter".
6. You will now be asked to confirm the selection. Press Y to confirm and continue, or N to abort.
- If you have not yet accepted the terms, you may be requested to read and accept the terms and conditions, so use the same Y to confirm or N to deny.
7. The certificate should be issued unless you encountered any issues (displayed in the command line interface). You can confirm in the IIS bindings that the HTTPS bindings are valid and using the new Let's Encrypt certificate.

A common reason why automatic renewals don't work when using win-acme is due to moving the win-acme executable (wacs.exe) to a different location or removing it altogether. If the scheduled task fires off every day but can not find the executable in order to perform the renewals then the certificate(s) will eventually expire. You can click on the scheduled task and view the path of the executable to make sure it is configured to the correct path location.
If the path location is incorrect, you can click on "Properties" within the Actions pane. Then click on the "Actions" tab and select "Edit". You can then change the path to the executable.
