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.
