After install 13.1.0, work WPViewPDF4 not more. Error message: it's with a wrong iexBitmaps unit compiled. In v13.0.0 all works perfect, what can i do ?
Search your system for wpcubed_pdf_plugin.dcu and remove any files that are returned.
Ensure you have wpcubed_pdf_plugin.pas on your search path, e.g. in your project folder. There is a copy of wpcubed_pdf_plugin.pas included in the ImageEn installation if you need it.
