Our ecommerce provider, MyCommerce (owned by Digital River Inc.) stopped paying us (and it appears, many others, see The Register) in August 2024.
We no longer trust any ecommerce provider. We do not have in-house expertise either in security or in tax regulations, so we are not able to handle payments ourselves. In view of this Qtrac Ltd. has now ceased selling individual licenses, and will be wound up in 2025.
We recommend that any customers with unacquired license keys acquire them as soon as possible. We hope to keep the website going for a while, and we hope to keep providing support as long as possible. All keys will continue to work as before. In particular, “full” keys will continue to work so long as the hardware/BIOS doesn't change, and annual keys will continue until their normal expiry date, regardless of hardware changes. Our software does not “phone home” and does not depend on our website. (In fact, some customers use our software entirely offline.)
We are very sorry for the inconvenience to our customers, and grateful for all those who have purchased our PDF comparison software over the past decade.
To provide continuity of use even after Qtrac Ltd. is wound up we are selling one-off perpetual licenses.
Perpetual licenses may be purchased only by existing customers (in the US and a few other countries) and this offer is only available until 2025-03-31. These licenses will be for comparepdfcmd version 2.5.0-pe, and for DiffPDF 6.2.0-pe, the final versions we plan to release.
There will be no maintenance or updates. The perpetual versions will not use a license key; they will not have an expiry date; they will not check which computer they are running on. Perpetual versions will not be affected by changes to the physical or virtual hardware (e.g., adding RAM or BIOS updates) or software changes (e.g., normal Windows updates). This means that perpetual versions may be copied to and used on any physical or virtual computer (running 64-bit Windows 7 or later), with no license key being necessary. Furthermore the perpetual license applies no limit on the number of copies that may be used (providing only that they are used by the purchasing company or organization).
The price of the perpetual licenses for comparepdfcmd and for DiffPDF
are 5 figure sums. Contact mark@qtrac.eu
for pricing and
purchasing information. For license terms see:
comparepdfcmd-license-pe.pdf
and diffpdf6-license-pe.pdf.
