Embedded Excel table in Word error

Hi,
When I use an intellisense add-in, if I insert an embedded table from an Excel file in Word, then I tried to modify it by double clicking on it, I got this error:
It does say in English:
"The program used to create this object is Excel. That program is either not installed on your computer or it is not responding."

You can reproduce it with this code:
```
public class Class1 : IExcelAddIn
{
public void AutoClose()
{
IntelliSenseServer.Uninstall();
}

public void AutoOpen()
{
IntelliSenseServer.Install();
}
}

```
thanks a lot for any advise,
Best regards
Sylvain
