PDFs will not display in IE unless IE Protected Mode is turned off RRS feed

  • Question

  • When I use IE 11 (fully updated Win 10 Home) and click on a PDF (i.e., irs.gov, "Form W9" pdf) the PDF will not open unless IE Tools/Internet Options/Security/ Enable Protected Mode is unchecked.  This is strange, since on my other PCs it is not necessary to uncheck Enable Protected Mode to view PDFs.

    I can right-click on a PDF and Save-As, which downloads the PDF.

    Other browsers (Firefox, Edge, Chrome, Tor) open and display PDFs as expected.

    I have checked all the usual suspects, installed multiple PDF programs ( Adobe Reader, etc.), Uninstalled / Reinstalled IE,  - all with no success.

    Can anyone help?
