When I click on an .xls file in explorer it asks for my authentication code -
then, it doesn't recognize my auth. code. I can still open the Excel program
File open and then click on the file and it works. Why can't I open in
Explorer (I used to be able to).

Try the usual fix(es) for this problem.

ToolsOptionsGeneral uncheck "Ignore other Applications"
Exit Excel and try again

If this doesn't work try to re-register Excel

Close Excel first and On the Windows Taskbar

1) StartRun "excel.exe /unregserver"(no quotes)OK.
2) StartRun "excel.exe /regserver"(no quotes)OK.
See the space between exe and /regserver

You might have to designate a full path to excel.exe.
In that case StartRun "C:\yourpath\excel.exe /regserver"(no quotes)OK.
