Sheet must be opened directly by Excel

When starting a macro in an existing spreadheet, I get the following error :

To work properly, this spreadsheet must be opened directly by Excel. It
appaers that you have opened it using Internet Explorer. Please download the
spreadsheet to your computer and open it using Excel.

Yesterday, it did work (since many years) and tody, suddenly it does not
work anymore.....

I Look at the file associations and I see something wrong, but I can not
correct it.....
