Problem in generating xml file

I have filled the relevant ITR 2. On validating, every sheet is OK and 'calculate tax' is also OK. However when I click the button "Generate XML" and "save XML" it says Run time error '-2146232576 (87131700)': Automation error I am not able to save the XML file. I have done macro enable before filling up the form. I have tried my best, but not able to do. Pls can anyone help. Regards, Debashis 9004061367
