Edited Unassigned: New-SelfSignedCertificateEx - "A parameter cannot be found that matches parameter name 'Encoding'" [80]

Hello,
I want to create a self signed s/mime cert.
To archiv this I use the Cmdlet New-SelfSignedCertificateEx, but i get the error "A parameter cannot be found that matches parameter name 'Encoding'".

__If I didn't use "-Path "M:\Certs\cert.pfx"" it works.__

Any ideas?

```
