To force the driver to be unloaded, which may be the only way to remove a progress dialog which won't otherwise go away (or to install an update of the driver), the easiest approach is to use the Task Manager to kill the process pdfSaver5.exe (or pdfSaver3.exe for version 3). You can also do it via one of the following Start...Run... command lines:

Version 5:

"C:\Program Files\Tracker Software\PDF-XChange 5\pdfSaver5.exe" /quit

Version 3:

"C:\Program Files\Tracker Software\PDF-XChange 3\pdfSaver\pdfSaver3.exe" /quit

Beginning with PDFXv5, you can show or hide the progress window via the //PDFX,Saver.ShowProgress,<bool> directive; see Saver

PDFXv3 did not offer such an option, although you could set it globally by modifying the following registry setting manually:

HKEY_CURRENT_USER\Software\Tracker Software\PDF-XChange 3.0\Drivers\pdfSaver

Within this path, you can set the value of the HideProgressWindow field to 1 to hide the progress dialog for all PDFX printouts generated by the current user. To do this for all users on the current machine, use the equivalent path in the HKEY_LOCAL_MACHINE hive, i.e.:

HKEY_LOCAL_MACHINE\Software\Tracker Software\PDF-XChange 3.0\Drivers\pdfSaver

Note that the PDFX print progress dialog may appear redundant or confusing when A-Shell is also displaying its own printer abort dialog.

The PDF-XChange driver that enables PDFX has its own user interface, which you may want to access directly for the purpose of familiarizing yourself with it and just to see what it looks like. Also, two functions (Bookmarks and Watermarks have parameters that are both too complex to pass via regular arguments, and are normally set once and then left alone. If you wish to use these functions, you will have to access the PDF-XChange driver directly. To do so, Go to the Windows Start menu, then Printers and Faxes, then PDF-XChange (or whatever name you're using), then Printing Preferences.

It is possible to use PDFX to PDF documents only in conjunction with A-Shell. See the following discussion on Licensing if you wish to generate PDF documents independently of A-Shell.

The software license granted to you by MicroSabio with your purchase of PDFX allows the use of the PDF-XChange system only with A-Shell. If you try to print to the PDF-XChange device from any application other than A-Shell, you will get conspicuous, annoying and un-defeatable PDF-XChange watermarks printed on all pages.

In order to use PDF-XChange outside the confines of A-Shell, you must purchase per-PC licenses for that purpose. These licenses are available to A-Shell users and resellers from PDF-XChange Co. Ltd. (previously Tracker Software), the developer/vendor of PDF-XChange. MicroSabio does not sell or support PDF-XChange; if you are interested in purchasing one or more licenses, please contact PDF-XChange Co. Ltd.
