I’m running SeoToolsforExcel in a Windows 7 machine running Office 365 (Excel 16) using VirtualBox.

Formulas like =HtmlMetaDescription(A2) do not work because I get the following error message:

Exception: WebException
Message: The service commited a protocol violation.
Section = ResponseHeader Detail = CR must be followed by LF

I already tried changing my config file, per a post here from 2013.
