In Windows 7 I used PDF24 to merge Word documents but it stopped working. When I try to open a file other than an image or a pdf, the document ends up in the print queue and nothing happens. I tried to uninstall and reinstall but 0path signals me an Exploit with an attempt to raise the privileges of the spooler and I think it blocks the installation of the virtual printer (the PDF24 printer at the end of the installation does not appear among the installed printers).
What could I do?
