Can't Open a Window

Ignition
1

A project I am working on has a nav bar where one button points to a screen “Popup_Help”. Trying to open this in the Designer and the Client view fail however. I know the window exists, I can see it in the Project Browser despite not being able to open it.

The error I get when trying to open it in browser is

SerializationException: Unexpected parsing error during binary deserialization.
caused by IOExceptionWithCause: java.lang.ClassNotFoundException: com.inductiveautomation.factorypmi.plugins.reporting.components.PDFViewer

Ignition v7.9.4 (b2017082911)

Whats going on here?

You need to install the reporting module, because there's a PDF viewer component on that window, which your current gateway/designer doesn't have (meaning, it can't open, because it doesn't know how to).
