Eliminate Macro Warnings in CDX Technologies Templates

26 December 2025 Bill-Hughes

Many CDX Technologies Excel templates rely on VBA macros to automate calculations, validations, and workflows. To protect users, Microsoft Excel displays security warnings when opening macro-enabled files from unknown or untrusted publishers. To ensure a seamless experience, CDX Technologies digitally signs its Excel templates using the Hughes Financial Services Inc. code-signing certificate. By adding this certificate as a Trusted Publisher, users can safely enable macros without repeated security prompts, subject to their organization’s security policies

This article explains why trusting the publisher matters and how to do it in just a few steps.

Why Excel Shows Macro Security Warnings

Excel macros can execute powerful commands, which is why Microsoft blocks them by default unless certain trust conditions are met. In particular, macros can run without warnings when:

  • The file comes from a trusted location (such as a designated trusted folder), or

  • The macro is signed by a publisher that has been added to Excel’s Trusted Publishers.

When a workbook is digitally signed but the publisher isn’t yet trusted, Excel displays a warning such as:

“Macros have been disabled” or “Security Warning: Macros have been disabled”

Adding the Hughes Financial Services Inc. certificate as a trusted publisher typically resolves these prompts for that user on that computer, as long as the certificate remains valid and organizational policies allow it.

Advantages of Adding Hughes Financial Services Inc. as a Trusted Publisher

Adding a trusted publisher provides both security and convenience.

1. Prevents Repeated Macro Execution Warnings

Once Hughes Financial Services Inc. is trusted, Excel will normally enable macros automatically in all CDX Technologies templates signed with that certificate, eliminating repeated prompts for those files. This behavior may still be constrained by your organization’s macro security policies or group policy settings.

2. Confirms File Authenticity

A trusted digital signature ensures:

  • The template came from Hughes Financial Services Inc.

  • The file has not been modified in a way that invalidates the signature since it was signed.

If a file is altered after signing so that the signature is no longer valid, Excel treats that signature as invalid and will not treat that file as trusted, even if the publisher itself is trusted

3. Improves User Experience

Users can:

  • Open templates without constant security interruptions.

  • Avoid confusion about whether it is safe to enable macros.

  • Reduce training and support issues related to Excel security prompts

4. Aligns with Enterprise Security Best Practices

Enterprise administrators should also configure macro policies (for example, “Disable all macros except digitally signed macros”) and restrict trusted publishers to vetted sources.

Trusting a verified publisher is safer than broadly disabling macro security. This approach:

  • Preserves Excel’s macro protection framework and default safeguards.

  • Limits trust only to known, approved publishers, in line with recommended enterprise controls.Enterprise administrators should also configure macro policies (for example, “Disable all macros except digitally signed macros”) and restrict trusted publishers to vetted sources.

How to Add Hughes Financial Services Inc. as a Trusted Publisher in Excel

Follow these steps the first time you open a CDX Technologies macro-enabled template.

Step 1: Open the CDX Technologies Excel Template

Open the .xlsm file provided by CDX Technologies. If you have just downloaded the file from the internet, be sure to unblock the file.

You should see a Security Warning banner indicating that macros have been disabled.

Step 2: Review the Security Warning and Digital Signature

  1. Click File → Info

  2. Under Security Warning, click Enable Content → Advanced Options (or a similar option such as Enable Content → More Options, depending on your version).

  3. In the security dialog, you can click Show Signature Details or View Signature to review the signature issued to Hughes Financial Services Inc. if you wish to verify the publisher.

  4. Optionally, you can click View Certificate from the signature details window to inspect certificate information before proceeding.

Step 3: Trust the Publisher

  1. In the security options dialog, select the option “Trust all documents from this publisher”.

  2. Confirm the selection when prompted. This adds Hughes Financial Services Inc. to your Trusted Publishers list for your user profile.

Step 4: Reopen the Template

Reopen the Excel file. Macros signed by Hughes Financial Services Inc. should now run automatically without additional warning messages on that user profile, provided your organization’s macro policies permit this

All future CDX Technologies templates signed by Hughes Financial Services Inc. will normally be trusted on this user account on that computer. If you still see warnings, your organization’s IT policies may be blocking macros even from trusted publishers, and you may need assistance from your administrator.

Important Notes

  • Trusting the publisher applies only to templates signed by Hughes Financial Services Inc.

  • If a file is altered or corrupted in a way that breaks the digital signature, Excel will treat the signature as invalid and will not treat that file as trusted, even if Hughes Financial Services Inc. remains a trusted publisher.

  • Trusted publishers are typically stored per user profile; in managed environments, IT may configure this centrally so you do not need to perform these steps yourself.

Need Help?

If you encounter issues trusting the certificate or if macros are still blocked after following these steps, contact CDX Technologies Support or your IT administrator for assistance. This ensures your templates run smoothly while remaining consistent with your organization’s security requirements
