Problem with IRS fill-in forms
Repeatedly, when trying to fill in US Internal Revenue Service forms in Acrobat DC Standard, I get a "bad file handle" message, and am unable to save the completed form. This did not happen with earlier versions of Adobe Acrobat and does not happen if I open the files in Acrobat Reader DC rather than the full version of Acrobat DC. I am using Windows 10.
Please provide the version of Acrobat DC installed on your machine.
To check version installed – Please refer https://helpx.adobe.com/acrobat/kb/identify-product-version.html
Also, please share the file (if possible) along with the error screenshot with us.
