There was a problem sending the command to the program
You might get this error message while clicking on Desktop shortcuts, Internet links, opening Word or Excel documents, etc.
Microsoft Office programs
It’s reported that this error is faced when we are trying to open Excel or Word documents. To fix that issue we have to change Dynamic Data Exchange or DDE setting. But first, create a system restore point before proceeding. In Excel:
Open Excel go to File and Click on OptionsThen click on advanceUncheck on Ignore other applications that use Dynamic Data Exchange (DDE)Then restart Excel (or Word).
If these do not help, then our author Kapil Arya has another suggestion: Windows provides several methods for transferring data between applications, Dynamic Data Exchange (DDE) protocol is one of them. The DDE protocol is a set of messages and guidelines. It sends messages between applications that share data and uses shared memory to exchange data between applications. The components inside Microsoft‘s productivity suite, i.e. Office uses the DDE protocol.
If disabling DDE via the UI does not work for you, try the following method using Windows Registry.
Press Windows Key + R combination, type put Regedt32.exe in Run dialog box and hit Enter to open the Registry Editor.
Navigate here:
In the left pane, export the ddeexec key by highlighting the key and click File -> Export. After exporting it to a convenient place, you can right-click over the same key and select Delete:
After deleting the key, you can close the Registry Editor. After a reboot, you would be no longer getting the error.
Internet Explorer
Most of the time setting Internet Explorer as the default web browser will fix the problem.
Open Internet ExplorerGo to Tools and click on Internet OptionsThen click on Programs TabThen Click on “Make Default”
If that does not resolve your problem then we might need to reset IE settings.
