PDF-XChange /Tools V4 Developer SDK's released !


We are pleased to announce the release of our award winning version 4 Software Developer SDK's for PDF-XChange and PDF-Tools.

Important : Please read this entire notice if you are interested in a PDF-XChange/Tools Version 4 upgrade from an earlier release - or you use the PDF-XChange Viewer SDK.

The most notable changes occur at this time to the PDF-XChange Drivers - though a very important change affects all products - we have now dropped support for Windows 9x/ME and NT and this should allow us to devote more development resources to the most popular remaining Windows operating systems - Windows 2K/XP/Vista - both 32 and 64 bit - though your Version 4 serial number will also allow you to use the Version 3 SDK should the need arise to support older Windows operting systems - but please note - no further Version 3 development will continue. 

More significant feature updates will occur later this year to the PDF-XChange/PDF-Tools Library functions in version 4.5x and of course all developer's owning any of our Version 4 PDF SDK's also gain access to the PDF-XChange Viewer SDK at no extra cost ! 

You will also need to upgrade to Version 4 if you are using the PDF-XChange Viewer SDK freely, by virtue of the fact that you own version 3 of one of our other PDF SDK's - from Version 2.037 of the Viewer SDK - new serial numbers are required and will only be provided to those developers who actually purchased a standalone V1/2.x version of the PDF-XChange Viewer SDK itself - or licensed PDF-XChange/Tools VERSION 4 SDK owners

Version 1 or 2.x SDK existing users !

Please note that this will be the very last opportunity for Version 1 or 2.x SDK owners to acccess  discounted upgrade options - from March 31st 2009 Version 1 or 2.x owners will be required to purchase a full, new PDF-XChange or Tools V4 SDK License with no discount being available.

If you own Version 1 or 2.x - please email us with your full company info, as used at the time of purchase and also your License info and we will advise how to access your upgrade options.

Version 3.x SDK existing Users !
