I apologize for the inconvenience this may have caused you. The situation you met may be caused by the connection problem between our server and your computer at that moment when you downloaded the upgrade patch. Anyway,I will feed this back to our relevant team for processing to make sure that our download server works steadily.
Currently,I suggest you download a full installer package of the latest version of Foxit PhantomPDF Business 5.4.2.0918 manually and install it.You have to uninstall your existing version first before install the newest version.
Following is the download link:
