The term 'Get-PfxData' is not recognized

• Version: 19.19.1

My machine is Window 7 64bit. I’m trying to create a signed Windows installer and getting this error (this is part of the stack trace):

Someone mentioned here that Get-PfxData is only available from Windows 8.1. Does that mean that code signing is not supported on Windows 7?

I can sign the installer with signtool.exe, but then the auto update won’t work, as it will cause a checksum mismatch. I also tried to download the last version of powershell from the github repo, with no success.

Thanks for your help!

Yes, you are right. The PKI module is available with Windows 8 and up.

But the build does not fail on my windows 7 machine and I haven’t set the publisherName on my own. I’m still trying to understand how it is and I don’t face the same problem as you.

While, indeed, when I execute “Get-PfxData” on powershell, I get the unknow command error.

What’s the version of your powershell (execute $psversiontable)?

Check https://blogs.technet.microsoft.com/heyscriptingguy/2013/06/02/weekend-scripter-install-powershell-3-0-on-windows-7/ for upgrading (moving to powershell 4 would be better, but powershell 3 should also work).
