Hello

I have installed an Excel Add-in, and it works fine, but every time I
close
Excel it dissapears and I have to install it every single time I open
Excel.

does some one know what could be wrong?

thanks so much

Did you try to add it in tools/addin menu?
you should have a tick near your addin name.

anyway you may try to put it to you addin:

Private Sub Workbook_Open()
AddIns.Add Filename:=ThisWorkbook.Path & "/YourAddinName.xla",
CopyFile:=False
AddIns("YourAddinName").Installed = True
End Sub
