Microsoft Excel Interview Question:

When I click on an Excel file to open it, the file opens but an error message is displayed that says a file with that name is already open and that I can not open two files open with the same name?

If you are sure it's not really happening (you may have Book1 open and then attempt to open a Book1 from another folder), then try re-registering Excel.
1. On the Windows taskbar, click the Start button
2. Choose Run
3. Type "C:Program FilesMicrosoft OfficeOfficeExcel.Exe" /regserver (include the quotes) -- adapt to fit your path.
Other things to check:
1. In Excel, choose Tools>Options.
2. On the General tab, make sure "Ignore Other Applications" is not checked
