This error is can happen when opening a file in Excel 2013, Word 2013, Publisher 2013, Access 2013, Visio 2013 or PowerPoint 2013. It makes it so you cannot open any of your office software, when you double click on the icon it will just hang and nothing comes up.
All that will appear is:
“There was a problem sending the command to the program”
To fix this error you need to open a run box (windows key + R) and run the following command:
winword.exe /R
Or which ever executable is not responding correctly. The /R parameter will re-register the program to the registry.
If this error happens with another program you will need to see if you can re-register that program or you may need to do repair installation.
