[Error] Windows SmartScreen prevented an unrecognized app

With the recent release of doPDF 8.5.937 it is possible that Windows 8/10 will show the following error when trying to install the downloaded setup:
"Windows SmartScreen prevented an unrecognized program from starting. Running this program might put your PC at risk."

This happens because doPDF is now signed with a more secure certificate (that uses sha256) but Windows sees this as a new certificate and thus displays the alert until the new setup is "establishing a reputation". To continue with the installation this is what you should do:
  • 1. Click on the "More info" link
  • 2. Next click on the "Run anyway" button to run the setup


This notice will disappear in up to a few days when Windows recognizes the reputation of the setup signed with the new certificate.
