This is complicated. But it CAN be attached to mail, no problem at all. It's just this is what you will see for a preview in many mail apps. Send it! The recipient must save it to their disk, then open in Reader, and all should be well.

Thanks for quick response. I sent it  found that it could be opened in Reader & it is readable as well ! but there is another serious issue, I could attach the file in e-signature software like Authentisign, the same error message appears & since it is not viewable, I could not drag the icon "Initial here" or "Signature here" to the place that I want.

This can only be viewed in Acrobat or Acrobat Reader. You can't use PDF tools made by other people. Basically, the form uses Adobe-only stuff. This is being phased out, thankfully.
