The English translation of the error message:
Excel, Opening files created with a version earlier than Excel 97 may not be successful. In this case, choose the Open all sheets option to successfully open.
It seems that you've tried to open an Excel file in a format that pre-dates Excel 97. If the file didn't open successfully you may find the Open All Sheets preference helpful.
You'll find this preference from File->Preferences... and the Third-party Data section.
