Question details

The user needs to fix a 'Compile error in hidden module' and resolve #BLOCKED! cell errors after moving an Excel workbook to a new computer.

How to Fix Excel Compile Errors and Broken Links After Moving a File

Product: Microsoft Excel
Device & OS: not provided
Scenario: Opening an Excel file containing macros, external links, and add-ins after transferring it to a different computer.
Observed behavior: Excel throws a 'Compile error in hidden module' upon opening the file, and cells with external references display a #BLOCKED! error.

Before you start

Ensure you trust the file and its external sources before enabling macros or updating external links on the new computer.

Solution 1Recommended

Clear or Update Missing VBA References

Use the VBA Editor to locate and remove broken references that trigger compile errors when the file is opened on a new PC.

When a workbook is moved to a new computer, the VBA project may look for libraries or add-ins in directories that no longer exist. Clearing missing references allows the code to compile correctly.

Open the VBA Editor

Press Alt + F11 on your keyboard to open the Visual Basic for Applications (VBA) Editor in Excel.

Access the References Menu

In the top menu bar, click on Tools and select References from the dropdown list.

Clear Missing Items

Scroll through the list of Available References and uncheck any items that start with 'MISSING:'. Click OK to save the changes.

Save and Restart

Save your workbook and restart Excel to confirm that the compile error has been resolved.

Save a Copy: It is good practice to save a backup copy of your workbook before making changes to VBA references.

Solution 2

Update Broken External Links to Fix #BLOCKED! Errors

Re-link external data sources to their new local paths to restore data and eliminate #BLOCKED! cell errors.

Solution 3

Resolve Add-in Architecture Mismatch (e.g., Aspel COI)

Ensure that your installed add-ins match the 32-bit or 64-bit architecture of your Excel installation to prevent hidden module errors.

Frequently Asked Questions

What does 'Compile error in hidden module' mean in Excel?

This error usually occurs when VBA code or an add-in is incompatible with your current version or architecture (32-bit vs. 64-bit) of Excel, or when a referenced library is missing on the new computer.

Why do my Excel cells show #BLOCKED! after moving the file?

The #BLOCKED! error often happens because Excel prevents access to external linked files that are stored in untrusted locations, or when the file path pointing to the original computer can no longer be found.

How do I check if my Excel is 32-bit or 64-bit?

Open Excel, click on the File tab, select Account, and then click on the 'About Excel' button. The top of the new window will clearly display whether your installation is 32-bit or 64-bit.
