Suddenly Excel started being unable to open its files. The notice is: there was a problem sending the command to the program
I tried several modes:
[*]the FIX-IT didnt work[*]Clear in the Trust Center > Advanced the box of ignore other application using DDE[*]manually changing the HKCR value in sheet open command

Everything seems correct, however to open a file I have to start excel first and open the file after having located it within excel.

Any suggestion?



Many thanks

Have you tried repairing the Office installation (via Programs & Features > Microsoft Office > Change in the Windows Control Panel)?

Hello,

YES, I did. No positive result.

Thank you for your interest.

Try this:
From the Windows Start menu, choose Run, and enter:

Excel.exe /UnregServer

Run that, then enter:

Excel.exe /Server

and run that.
