Not sure what your problem is but maybe file association is messed up.

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.
