Try the usual fix for this.

ToolsOptionsGeneral Uncheck "Ignore Other Applications"

If no joy with that................

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(quotes
required)OK.

I've used Excel for years. A few days ago I couldn't open an Excel file
attached to an email from a coworker. Since then clicking on any shortcut or
an Excel file attached to an email only loads the Excel program, but doesn't
load the requested worksheet file - or even a blank worksheet. I've checked
the settings (which had been working fine) and find no problem.

With Excel open, I can click "open" and locate any file and load it without
a problem. I just can't get files to load from any shortcut or from an
email. Word files and other types of files work fine in their appropriate
programs.
