Glad to hear it's working for you.

Just to clarify for anyone else wondering about the password prompt:

  • If you try to install the .p12 file by double-clicking it in Windows Explorer, Windows will ask for a password. Do not do this.
  • You must use the ZenZefi-UI tool as described above. Click Import inside the application, and it will handle the certificate bundle without requiring you to input a password manually.

If the certificate doesn't appear active immediately after importing, try restarting the ZenZefi Backend Service in Windows Services (services.msc) or simply reboot your laptop.
