1] Run Excel as an administrator

Sometimes the problem occurs due to administrative privileges. To check this, launch Microsoft Excel as administrator and then see if you get the same error message. To do that, right-click on the Microsoft Excel shortcut and select Run as administrator.

If this fixes your problem, you can make Excel always run as administrator.

2] Make the Excel folder empty

When you create a new spreadsheet or edit the existing one, Microsoft Excel creates its unsaved copy in the Excel folder. This is how Excel recovers your unsaved document when your computer or Excel crashes suddenly. These files remain in that folder until you save your spreadsheet. By default, these temporary files are located in the Roaming folder. Apart from that, some temporary cache files may also be created in that folder.

Make the Excel folder empty and check if this fixes your problem. To do that, follow the steps below:

Open the Run command box by pressing the Win + R keys.
Type %appdata% and click OK. This command will directly open the Roaming folder on your C drive.
Now, open the Microsoft folder and then open the Excel folder. You may see some temporary files and folders there.
Move all the files and folders to another location in order to make the Excel folder empty.
Open Microsoft Excel and see if the problem disappears.

If the problem still occurs, you can move the files back to the Excel folder.

3] Change your default printer

Sometimes, the problem occurs when Excel is not able to access the default printer. To check this, change your default printer. You can also make a virtual printer as your default printer, like Microsoft Print to PDF or Microsoft XPS Document Writer. After performing this step, check if the problem occurs.

4] Troubleshoot Excel in Safe Mode

There might be some problematic add-ins in Excel that are causing the problem. To check this, you have to troubleshoot Excel in Safe Mode. Check if you are able to launch Excel in Safe Mode. If yes, some of your Add-ins are the culprit.

To launch Excel in Safe Mode, open the Run command box and type excel /safe. After that, click OK. This will open Excel in Safe Mode. Now follow the steps below:

Go to “File > Options.”
Select Add-Ins from the left side.
Click on the Manage drop-down and select COM Add-ins. Click Go.
Deselect anyone add-in to disable it and click OK.
Close Excel in Safe Mode and launch Excel in normal mode. See if the issue appears. If yes, repeat the above steps to disable another add-in and then launch Excel in normal mode again.

The above steps will help you find the problematic add-in. Once you find it, remove it from Excel.

5] Troubleshoot in a Clean Boot state

If there is no problematic add-in in Excel, the issue might occur due to a conflicting background or startup app. You can easily identify that program by starting your computer in a Clean Boot state. After starting your computer in a Clean Boot state, launch Microsoft Excel and see if the “Not enough memory to run Microsoft Excel” message appears. If not, there is a program that is conflicting with Microsoft Excel due to which Excel is displaying this error.

To identify that program, enable some of the disabled programs in the Clean Boot state, and then start your computer in a normal state. Launch Excel after starting your computer in the normal state and see if the error occurs. If yes, some of the programs you have just enabled are causing the problem. To identify those programs, disable the enabled programs one by one and launch Excel each time you disable a program. This will help you identify the problematic startup application.

6] Change the Trust Center settings

If you are unable to attach an Excel in Outlook or if you are getting the error message after opening the Excel file from Outlook or another email client, change the Trust Center settings and see if it works.

Open Microsoft Excel.
Go to “File > Options.”
Now, go to “Trust Center > Trust Center Settings” and select Protected View from the left side.
Uncheck all the options and click OK.
Now, open the Trust Center Settings again and select File Block Settings from the left side.
Uncheck all the options and click OK.

7] Toggle the Dynamic Data Exchange (DDE) mode

This solution is also for the users who are receiving the error message “Not enough memory to run Microsoft Excel” while attaching an Excel file to Outlook or while opening certain Excel files.

Launch Microsoft Excel.
Go to “File > Options > Advanced.”

Click OK and close Microsoft Excel.
Wait for a few seconds and launch Excel again.
Now, disable the “Ignore other applications that use Dynamic Data Exchange (DDE)” option.
Click OK and close Excel.

This should help. If not, try the next solution.

Now, click Start to start the service.
Click Apply and then click OK.
