Office 365 ProPlus is being renamed to Microsoft 365 Apps for enterprise. For more information about this change, read this blog post.

Quantum XL is fully compatible with Windows 32bit and 64bit. However, at the time of writing Quantum XL must be running on 32bit Office/Excel. By default, the Office installer will install the 32bit version. However, if you would like to double check, then follow these steps. Note: Excel 2007 and earlier are all 32-bit. Instructions Support – Do I have 32bit or 64bit Excel/Office Read. Excel is an amazing tool for analyzing and visualizing data sets. To visualize and make report we often need to save small chunks of data. These small chunks of data grow over time and make the files heavier.

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.

Resolution

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.

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

Option 1: 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.

Option 2: 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 3: 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:

Option 4: 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.

Option 5: 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.

Windows 8

1. On the Start screen, type Control Panel.
2. Select or tap Control Panel.
3. Select Default Programs, then select Set your default programs.
4. Select Excel, then select Choose default for this program.
5. On the Set Program Associations screen, select Select All, and then select Save.

Windows 7

1. Select Start, then select Control Panel.
2. Select Default Programs.
3. Select Associate a file type or protocol with a specific program.
4. Select Microsoft Excel Worksheet, then select change program.
5. Under Recommended Programs, select Microsoft Excel.
6. If Excel does not appear in this list, select Browse, locate the Excel installation folder, select Excel.exe, then select Excel.

Option 6: 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.

Option 7: Repair Office

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

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:

Option 8: 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 none of the above options works, please make sure Excel is not in Compatibility mode.

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