Instead, You must write

  excel = WIN32OLE.excel("Excel.Application")

  excel.Visible = true

 

For more,

   installer = WIN32OLE.new("WindowsInstaller.Installer")

   record = installer.CreateRecord(2)

   record ["StringData", 1] = 'dddd'

   installer = WIN32OLE.new("WindowsInstaller.Installer")

   record = installer.CreateRecord(2)

   record.setproperty("StringData", 1, 'dddd')
