Every time I try to open any files by, associated with EXCEL , double clicking on it , a pop up window opens showing
"There was a problem sending the command to the program."
Each time I need to open any file I have to open EXCEL first and then drag and drop the particular file to open it. Then it opens as usual.
But every time I double click on the same file this pop-up window shows up. Excel starts but it does not open the file. I am using Excel 13.
Please suggest me some way around.
