Important Security Update issued 30 December 2009:

te to release 2.044 recommended.
After consultation with Secunia Research ( Tracker Software Products Ltd has issued an update to all versions of its popular Free/Licensed PDF-XChange Viewer product family including both end user and developer product ranges.
On December 29th 2009, Secunia notified Tracker after testing, of the potential for malicious code to be executed to compromise users systems via PDF files, using a very specific means - though no such exploitation is known to have occurred to date, we felt we should act with some urgency to protect our clients.

All PDF-XChange Viewer and Viewer SDK versions prior to release 2.044
should be updated to a later release.

The PDF-XChange Viewer (FREE or PRO) is also offered as part of the PDF-XChange Lite,
Standard and PRO, and PDF-Tools product bundles - users of these products are urged to
update therefore also.
Developers using the PDF-XChange Viewer ActiveX SDK are urged to also update their clients
systems as soon as practical with a later release of their products incorporating the Viewer
SDK Version/Build 2.044 or later.

Security Vulnerabilities in Acrobat Reader - is PDF-XChange affected ?

Recently we have been asked if the PDF-XChange Viewer is vulnerable to the latest attempted hack into users systems by groups attempting to exploit weakness in the Adobe Acrobat Reader, we have researched this thoroughly and we are pleased to confirm we are not !

The Adobe vulnerability is caused by some buffer overflow issue within their JBIG2 decoder. PDF-XChange uses our own JBIG2 decoder and therefore we are not subject to any code directed at exploiting flaws/weaknesses in Adobe's JBIG decoder

More information regarding Adobe vulnerability can be found at or

Any clients and users wishing to discuss this or any other related issue should feel free to contact us at any time.

Many thanks

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 !

If you have not already registered - you will need to go here and register to acccess your upgrade options - these will be available from a link on the registered users web page.

If you have already registered - please login here to access your upgrade options.

If you cannot recall your login info - it may be requested here 

Should you have any problems registering or using your login - please email us with your full company and original purchase info - including (but not only) your serial number.
