Resolve Compile Error in Hidden Module in Excel: Causes & Solutions

The hidden module in Excel refers to a container with VBA codes, custom queries, and complex macros. The compile error in a hidden (protected) module in the Excel worksheet usually occurs when doing different activities on a macro-enabled sheet, such as merging .xls files. The error can result in macros execution failure. You need to quickly resolve this compile error to restore full functionality of the VBA code. Below, we’ll be discussing the solutions to fix this Excel error. But before that, let’s see why this error occurs.

You may encounter the Compile error in hidden module due to one of the following reasons:

The code in the workbook is not compatible with the Excel application.
Manual queries created in a previous version are no longer compatible with your current version of Excel.
Missing references.
Invalid .exe files (control information cache files) are automatically created with ActiveX control insertion in Excel file.
Protected module is corrupted.
The workbook with hidden module is damaged or corrupted.
Incompatible add-ins.
Incompatible Excel file version.
The module is protected or password-protected.
Missing or corrupted mscomctl.ocx file.

Excel can throw the compile error while compiling the code that exists in the protected module. So, first check the error and identify the hidden module that is creating the issue. You can unprotect the module. Also, ensure that you have permission to access the VBA code in the module. If the error still exists, follow the below troubleshooting methods.

Method 1: Re-register ActiveX Control Files or mscomctl.ocx Files

You can get the compile error in the Excel file, containing the VBA code related to ActiveX controls or OCX files. The ActiveX control files and OCX files (mscomctl.ocx files) are the components of Microsoft’s standard controls library. The compile error in the hidden module can occur if these files are missing. In this case, you can use the Regsvr32 tool to re-register the OCX files. The Regsvr32 is a command-line utility to register and unregister OLE controls in the Windows registry.

Method 2: Delete .exd Files

The .exd files are temporary files created by Excel when inserting ActiveX controls objects. These temporary files can lead to a compile error if they are corrupted. So, if this issue has occurred, particularly in the Excel file containing ActiveX controls, then deleting .exd files might fix the issue. To delete the .exd file, follow the below steps:

First, open the Run window by pressing the Windows+R keys.

In the Run window, type %appdata%.

In the Roaming window, click on the Microsoft option.

Under Microsoft, you will see a list of folders. Search and click on Forms.
Right-click on a file with .exd extension and select Delete.
Once you delete the .exd files, restart your Excel application.

Method 3: Rollback the Office Updates

MS Office updates or upgrades may also cause the compile error in hidden module in Excel. If the error has occurred after downloading the recent Microsoft Office updates, try reverting to the previous version or uninstalling the recent updates to fix the issue.

Method 4: Unselect Missing References

The compile error in hidden module determine path in Excel can also occur if your file contains a reference to object library/type library, which is labelled as Missing. You can locate, check, and uncheck the references marked as ‘Missing’ to fix the issue. Here are the steps:

Open your Excel and press Alt + F11 keys.
The Visual Basic Editor is displayed.

Go to the Tools option and then click References.

In the References-VBAProject window, under Available References, search and unselect the references starting as “Missing”.

Click OK.

Method 5: Check the Code in Module

The compile error in hidden module can occur if there are issues in the code within the module. The problems include incorrect or missing syntaxes, missing parameters/references, or the code contains incompatible functions or a wrong name of the object. You can check and fix these issues in the code by opening the VBA editor.

Method 6: Check and Remove Add-ins

In Excel, the compile error in macro-enabled files can also occur due to incompatible add-ins. You can check and disable the add-ins in Excel using the below steps:

First, open the Run window and type excel /safe and then click OK. The Excel application will open in safe mode.
Now try to open the affected Excel file. If it opens without the error, then check and remove the latest installed Excel add-ins.
Navigate to the File option and then select Options.
In the Excel Options window, click Add-ins.

Under Add-ins, search and select the latest add-ins, and then click on Go.
In the Add-ins window, uncheck the add-ins and then click OK.

Restart Excel and then check if the error is fixed or not.

Method 7: Repair the Corrupt Excel File

Corruption in the Excel file can affect the macros in the hidden module, which may result in the compile error. In such a case, you can try repairing the Excel file using Microsoft’s inbuilt utility -Open and Repair. To use this tool, follow these steps:

Open your Excel application.
Click the File tab and then click Open.
