Invalid xml: line 64 schedule hp state code

Thank you for your reply. I validated the XML. Got the message "*Sheet House Property (HP) is ok". Then generated XML, however, getting the same message while uploading. Any other solution that you might have?

Thank you again for your reply. I tried this also, and it did not work.

Few other websites had suggested that downloading Microsoft .NET Framework 3.5 can help resolve the issue. I did that from this website: https://www.microsoft.com/en-in/download/details.aspx?id=21

And it worked! I could successfully upload the ITR2 XML!
