In addition...

Assuming the file function.xla is already available in the default Addin
folder
If I run those lines in my script
Set appXL = CreateObject("Excel.Application")
appXL.Application.Addins.Add("addin.xla").Installe d = True

I get this error
Err.description: Unable to get the Add property of the AddIns class

Any idea ? Does it mean the Addin collection cannot b manipulated into
vbscript ?

Thanks
