Question details

The user needs to unblock macros in an Excel workbook generated by Arena Simulation, as the macros remain blocked despite adding the folder to Excel's trusted locations.

How to Unblock Macros in an Excel Workbook from Arena Simulation

Product: Excel
Device & OS: not provided
Scenario: Opening and running a macro-enabled Excel workbook that was exported or generated by third-party software (Arena Simulation).
Observed behavior: Excel consistently blocks the macros from running, ignoring the modified Trust Center settings and the trusted location status of the folder.

Before you start

Ensure you have saved a local copy of the workbook to your computer and close Excel completely before attempting to modify the file's properties.

Solution 1Recommended

Unblock the Workbook via Windows File Properties

Windows automatically blocks macros in files originating from another computer or third-party software using a feature called 'Mark of the Web'. You must unblock the file directly from its Windows properties.

When files are generated by external applications like Arena Simulation, Windows flags them as potentially unsafe. This flag overrides Excel's Trust Center settings, meaning you must remove the block at the system level before Excel will allow the macros to execute.

Save the workbook locally

Download or move the Arena Simulation workbook to a local folder on your computer's hard drive.

Open File Properties

Open Windows File Explorer, right-click the Excel file in question, and select 'Properties' from the context menu.

Unblock the file

Navigate to the 'General' tab. Look for a security warning at the bottom of the window. Check the 'Unblock' box, then click 'Apply' followed by 'OK'.

Verify Trusted Locations: After unblocking, make sure the file remains in the folder you previously designated as a Trusted Location in Excel's Trust Center.

Solution 2

Verify Trust Center Macro Settings

Ensure your Excel macro settings are properly configured to allow macros to run, especially if they are digitally signed or placed in trusted folders.

Frequently Asked Questions

Why does Excel block macros even in a trusted location?

Windows applies a 'Mark of the Web' (MOTW) to files originating from other computers, internet downloads, or certain third-party applications. This security feature blocks macros at the Windows file system level before Excel's Trust Center even evaluates the folder location.

Where is the Unblock option in Excel?

The 'Unblock' option is not found inside the Excel application. You must close the spreadsheet, right-click the file in Windows File Explorer, choose 'Properties', and locate the Unblock checkbox at the bottom of the 'General' tab.

What if the Unblock checkbox is missing from file properties?

If the Unblock option is not visible in the file properties, the file is not currently blocked by Windows MOTW. In this case, check your Excel Trust Center settings to ensure macros are not being disabled globally by your organization's IT policies.

Can I bypass the macro block by saving the file differently?

Yes, opening the file (even if macros are disabled) and saving it under a new name using 'Save As' into a trusted location can sometimes strip the security block, allowing the macros to run normally the next time you open the new file.
