Information sheets

For Trusted Contacts  – outlines about how we'll work with you and your IT support team to migrate your Landonline users.

For IT support – outlines how to access, store, test and migrate the software within your firm’s IT environment.

Before you begin:

  • You may need to update the firewall rules to ensure the DC Loader can call Entrust to retrieve the DC. The following addresses and ports should be opened
    • 829
    • 389
    • 443
    • 80
  • You will need to ensure that TLS 1.2 is enabled (Windows has this is ‘on’ by default but it may have been disabled for some reason)
  • DC Loader 3.1 and Digisign 3.1 are compatible with Windows 8.1; Windows 10 and Windows 11 and most Windows Server versions
  • The DC Loader installation software comes packaged with a Java installer.  If you have anything in place that could prevent Java from installing, the installation may fail or be incomplete.
  • If installing DC Loader to a controlled environment, you’ll need to pre-create a ‘C:\LINZ Certificates folder’ and provide Authenticated Users with Read/Write permissions.
  • Please familiarise yourself with the Landonline Terms and Conditions re Digital Certificate user obligations:

For software downloads please refer to Download or renew your two-year Digital Certificate.

Hints and tips

  • Once the DC Loader is installed in your IT environment - behind the firewall - you can create a shortcut to it, and share this shortcut with your Landonline users. This will avoid having multiple copies of the installer on your system.
  • The DC Loader defaults to the C drive. If your firm chooses another pathway, you will need to ensure users have full read/write permissions to that folder for two reasons:
    1. Future DC installations will overwrite existing DCs
    2. Inadequate permissions may cause issues when a DC is used to sign

Note: Using a different location to the default C:\, may result in users needing to browse and select the new file path each time they need to enter their passphrase when signing.
