Symptoms

When you double-click an icon or file name for a Microsoft Excel workbook, Excel starts and then displays a blank screen instead of the file that you expect to see.

Try the following options to help recover your document. Select the image or header to see more detailed instructions about that option.

Important

Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

Resolution

To resolve this problem, try the following options, as appropriate, in the given order.

Option 1: Ignore DDE

This problem may occur if the Ignore other applications that use Dynamic Data Exchange (DDE) check box in Excel options is selected.

When you double-click an Excel workbook in Windows Explorer, a dynamic data exchange (DDE) message is sent to Excel. This message instructs Excel to open the workbook that you double-clicked.

If you select the 'Ignore' option, Excel ignores DDE messages that are sent to it by other programs. Therefore, the DDE message that is sent to Excel by Windows Explorer is ignored, and Excel does not open the workbook that you double-clicked.

To correct this setting, follow these steps.

Note

This step can be skipped for Excel 2019 and Excel O365.

1. In the upper-left corner of the Excel window, select File > Options.
2. On the left side of the Options window, select Advanced.
3. In the Advanced window, scroll down to the General section.
4. Clear the Ignore other applications that use Dynamic Data Exchange (DDE) check box, and then select the OK button at the bottom of the window.

Note

For more information about how to turn off DDE, see 'An error occurred when sending commands to the program' in Excel.

If these steps do not resolve the problem, continue to Option 2.

Option 2: Repair User Experience Virtualization (UE-V)

If you are running Update User Experience Virtualization (UE-V), install Hotfix 2927019. To do this, see the following Knowledge Base article:

2927019 Hotfix Package 1 for Microsoft User Experience Virtualization 2.0

If you are not sure whether you are running UE-V, examine the program list in the Programs and Features item in Control Panel. An entry for 'Company Settings Center' indicates that you are running UE-V.

If these steps do not resolve the problem, continue to Option 3.

Option 3: Reset file associations

To check whether the file associations in the system are performing correctly, reset the Excel file associations to their default settings. To do this, follow the steps for your operating system.

Windows 10 and Windows 8.1

1. Locate the file that is opening incorrectly, and copy it to your desktop.
2. Right-click the file, and select Properties.
3. On the General tab, next to Type of file, the type of file will be indicated within parentheses. For example, (.docx), (.pdf), or (.csv).

The Opens with command shows you which app the file is currently associated with.

To open this type of file in a different app:

1. Select Change.
2. Select More apps.
3. Select the desired app, then select the Always use this app checkbox.
4. Select the OK button.

Try to repair your Office programs. To do this, follow the steps for your installation type and operating system.

For an Office 365 or Office 2019 Click-to-Run installation

Windows 10

1. On the Start screen, type Settings.
2. Select or tap Settings.
3. In the Settings window, select or tap Apps.

Windows 7

1. Select Start, then select Control Panel.

2. double-click Programs and Features.

3. Select Microsoft Office 365, then select Change.

4. Select Online Repair, then select Repair.

Note

You may have to restart your computer after the repair process is complete.

For an Office 2013, Office 2010, or Office 2007 installation

To repair Office 2013, Office 2010, or Office 2007, follow the steps in the following Office website topic:

If these steps do not resolve the problem, continue to Option 5.

Option 5: Turn off add-ins

Excel and COM add-in programs can also cause this problem. These two kinds of add-ins are located in different folders. For testing, disable and isolate the conflict by turning off each add-in one at a time. To do this, follow these steps:

1. On the File menu, select Options, and then select Add-Ins.
2. In the Manage list at the bottom of the screen, select COM Add-Ins item, and then select Go.
3. Clear one of the add-ins in the list, then select OK.
4. Restart Excel by double-clicking the icon or file name for the workbook that you are trying to open.
5. If the problem persists, repeat steps 1-4, except select a different add-in in step 3.
6. If the problem persists after you clear all the COM Add-ins, repeat steps 1-4, except select Excel Add-Ins in step 2. Then, try each of the Excel add-ins one at a time in step 3.

If Excel loads the file, the add-in that you last turned off is causing the problem. If this is the case, we recommend that you visit the manufacturer's website for the add-in to learn whether an updated version of the add-in is available. If a newer version of the add-in is not available, or if you don't have to use the add-in, you can leave it turned off.

If Excel does not open the file after you turn off all the add-ins, the problem has a different cause.

If these steps do not resolve the problem, continue to Option 6.

Option 6: Disable hardware acceleration

To work around this problem, disable hardware acceleration until a fix is released by your video adapter manufacturer. Make sure to check regularly for updates to your video adapter driver.

To disable hardware acceleration, follow these steps:

1. Start any Office 2013, 2016, 2019, or O365 program.

2. On the File tab, select Options.

3. In the Options dialog box, select Advanced.

4. In the list of available options, select the Disable hardware graphics acceleration check box.

   The following screenshot shows this option in Excel.

5. Select the OK button.

Note

For more information about hardware acceleration, see the following Knowledge Base article:

2768648 Display issues in Office 2013 client applications

Option 7: Minimizing and maximizing the window

Minimizing and then maximizing the window can sometimes refresh the Excel page and cause any hidden data to appear.

1. In the top-right corner of the Excel spreadsheet, select the minimize button.
2. In the task tray, right-click Excel, and then select your spreadsheet. (Or double click the Excel icon.)

After your sheet is maximized, your data may appear.

Option 8: Check for hidden sheets

An Excel sheet may inadvertently have been saved as a hidden document. To check this, follow these steps:

1. Go to the View tab.
2. Select Unhide.
3. Select a workbook from the list.
4. Select OK.

If you still experience this problem after you try all these options, contact Microsoft Support for additional troubleshooting help.

If none of the above options works, please make sure Excel is not in Compatibility mode.
