Installing certificate files on a computer can be done using .NET methods with any version of PowerShell. This would import a certificate file to your personal store:
# importing to personal store $Path = 'C:\Path\To\CertFile.cer' $Store = New-Object -TypeName System.Security.Cryptography.X509Certificates.X509Store -ArgumentList My, CurrentUser $Store.Open('ReadWrite') $Store.Add($Path) $Store.Close()
You can verify it by opening the certificate manager:
PS C:\> certmgr.msc
If you’d like to import the certificate to a different store location, simply adjust the arguments you submit when creating the store object.
