Are You Experiencing Issues with Version 11?

We regret to inform users that some issues have been identified with the new version 11 of our software products, including:

• Windows not recognizing the application as the default PDF handler.

• Printers not functioning correctly after the update.

• Issues with the new file explorer, including missing locations, or loss of access to shared network drives and cloud services.

• License keys not transferring correctly following our migration from ..\Tracker Software\.. file paths to ..\PDF-XChange\.. file paths. Reapplying the license key should resolve these instances.

• Issues related to changes that were made to default registry/folder names (see below for further information).

While these were primarily a collection of smaller issues rather than a single critical defect, the decision was made to make the V11 installers temporarility unavailable as a precautionary measure. Users who have experienced any of these issues should completely uninstall the software using the Windows Control Panel, restart their devices, and reinstall V10.8.5 to use until the issues in V11 are fully resolved. V10.8.5 is available to all users with maintenance that covers V11. You can access the installers to that version via your account page, which is available here. However, if you have not been experiencing any issues with V11, then there is no need to roll back to an earlier version of the software.

A PDF file detailing all file path/registry/folder name changes that occurred when moving from V10 to V11 is available here.

We are continually striving to optimize the checks and procedures that we carry out when we prepare and release new builds. We sincerely apologize for any issues that users experienced during this transition between major versions. Please rest assured that we are working on resolving them, and also on optimizing your experience with similar transitions in the future.

Thank you for your patience while we resolve these issues.

We have introduced a new release cadence that will include periodic preview builds available to existing, licensed users of PDF-XChange who would like to help shape the software. 

You will have access to all the new, fresh features upcoming in the released public versions, bug fixes and feature refinements. This will help us refine and even add functionality, where deemed appropriate, based on your input and feedback.

If you are interested in joining the preview program, then please email support@pdf-xchange.com with the subject line “Early Access Program – Registration,” and we will assist you with setup.

Participation requires a valid, current license for PDF-XChange, and an active account on our website.

In order to facilitate this, you will receive an email containing a link to download a preview version, along with notes highlighting areas where feedback is particularly valuable. Preview versions are designed to be installed alongside your existing production installation, so both can remain available and be used independently without compromising their respective useability.

NEW Release - Build 10.8.5.410 - Available Now 21.04.2026

Axios NPM Supply Chain Compromise: Malicious Packages Deliver Remote Access Trojan - PDF-XChange Unaffected

Security Bulletin Apr 3,  2026

On March 31, 2026, attackers compromised the official Axios package on the Node Package Manager (npm) registry. Axios is one of the most widely used open-source libraries for making web requests, with over a hundred million downloads per week. It's embedded in web applications, mobile apps, backend services, and automated build pipelines across virtually every industry.
https://www.sans.org/blog/axios-npm-supply-chain-compromise-malicious-packages-remote-access-trojan

PDF-XChange uses Axios libraries on our website. However, we at PDF-XChange had not yet completed our review and testing of the latest release and therefore were yet to either approve or implement the release that was compromised. 

We have thoroughly reviewed our servers, and no malware was detected. Consequently, we are pleased to confirm that our systems were completely unaffected.

Best regards,
PDF-XChange Co. Security Team

Web site Service updates - Monday 9th March 2026

Web site Services updates - Monday 9th March 2026.
Over the past months we have experienced a huge increase in attempts by malicious 3rd party actors to disrupt service for our primary domains and web site. In particular at specific times each week we have noticed automated attempts to break down our defences and it has been necessary this weekend to take action to ensure that both ours and our clients services and data are always adequately protected.

This is a regrettable but not surprising consequence of the staggering increase in our sales over the past 2 years - up over 100% for our most popular products - as many of our competitors have ceased to provide their products on anything but the 'subscription model - forcing clients to pay greatly increased (and far more lucrative for them) monthly or quarterly fees,  should they wish continue to use their software products and applications. It is our firm intention to continue to offer our products on a perpetual license, with no mandatory monthly, quarterly or annual fees.

During the course of today as these services are updated and propagated you may notice a temporary deterioration in response times to web site requests and  delivery - we sincerely apologise and will do our utmost to keep any interruptions to our services to the absolute minimum.

Thank you for your understanding and patience as we act to improve our security and defences against these criminal and nefariously motivated groups.
