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.
