You may have checkmarked ToolsOptionsGenerl "Ignore other application" which
would cause you to open a distinct instance of Excel for each file opened by
double-click.

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.

Works a treat, funny I don't recall opening the sheets that way before , so
I guess memory loss is settling in as I do this monthly oh well.
