Hello, greetings from Switzerland,

The script is stopping because an error occurred.

hi @ybornick

What client are you using
What command are you running
Describe your setup rather than just pasting a log file (logs without context are not useful).
If you are following instruction from a wesbite paste the link so people can review.


Hi @ahaw021

Sorry for not having posted the right informations. I run a DOS-batch that launch a powershell script. The script is too long to be inserted here :frowning: I’ve uploaded both files on

My PC is Windows 7 Pro with PowerShell 4.0 Could it be the problem, too old OS ?

Thank you,


hi @ybornick

No problems and thanks for taking the time to share the script as it helped resolve the problem (hopefully).

Are you aware that this script is using a library called ACMESharp?

I can’t see anywhere in the script where this is installed (maybe this was a step Alt-N missed)

MDaemon is a great product and the script looks pretty solid.

PowerShell 4 is fine.

Download and Install ACMESharp from here:


Once ACMESharp is installed you should be able to call it as a module

The .bat file is a wrapper for the script but doesn’t install ACMESharp for you


Hi @ahaw021

Thank you for the reply. The problem is solved after installation of ACMESharp. Before that I had to install PowerShell 5.1 (KB3191566-x64) and Windows Management Framework 5.1 (KB3191566-x64) and the to type in PowerShell “Install-Module -Name PowerShellGet -Force” and then to type “Install-Module -Name ACMESharp”. After all that the MDaemon script worked fine :slight_smile:

Thank you very much for your help !
