Starting in 22.214.171.124, Atalasoft replaced the underlying Foxit library used
for PDF rendering (PdfReader a.k.a. PdfDecoder) and PDF Text Extraction
(PdfTextDocument and related classes)
Users with existing PdfReader licenses (PRP2 / PRPX2 serials) were provided
with new PRP2 / PRPX2 serials for use in 11.0
As of September 2018, our contractual relationship with Foxit will end, and
the old PDF Reader libraries used in 10.7 and older will no longer be sold or
Additionally, as of DotImage 126.96.36.199, the Foxit libraries will no longer be
included as a part of DotImage
What does this mean for you:
If you purchased DotImage PdfReader add-on after the release of 11.0 and are
using 11.0 or newer along with PRP2 and/or PRPX2 serials, nothing changes for
If you were under active maintenance and had existing PdfReader licenses
(PRS2 / PRSX2 serials) you should have received your updated PRP2 / PRPX2
serials.. If you have not, you can create a support case with your existing PRS2
/ PRSX2 serial and a request for your 11.0 replacements and they will be
In any case, if you're actively developing and deploying with 11.0 or newer,
you likely will not see any changes (except for very special circumstances ..
in those cases if you have a special case where you've been granted a temporary
waiver to use Foxit engine in 11.0, please contact support)
If you're using an existing license under an older product (10.7 or older)
and your licenses are under active maintenance, you can continue to use the
older version (though support always suggests staying current for the best
features and all the latest bug fixes).
However, if you have existing PRS2 / PRSX2 licenses and pre-11.0 deployments
and require additional SDK or DEV/Build or server licenses, we can no longer
sell serials for those components.. You would need to acquire new PRP2/PRPX2
serials and upgrade your applications to use 11.0.
If you have any questions about how this change will affect you, your
applications, your developers, your licensing, etc.. please create a support
case or reach out to your Atalasoft sales representative and we will assist
As always, if you need help in upgrading to 11.0 please create a support case
and we will assist you.
Q: Do I have to upgrade my application to 11.0 or later?
A: No: you can stay with your current version so long as you
keep your maintenance active and you are not running into any bugs that require
a fix from DotImage not present in 10.7.0.13 or older
Q: Why should I continue to pay for maintenance/renewals if
I want to stay with an older version?
A: So long as you keep your maintenance /renewals, you can
continue to develop and deploy solutions using the older version. If you stop
your maintenance / renewals, our license terms say you must stop all new
development and may not deploy any new applications (though you can continue to
maintain an existing deployment). Also, See below: support will still assist you
with older versions.. there are just some limits on what we can do.
Q: What support is available for older versions?
A: So long as you are under active maintenance, you're
entitled to support through our case portal and via telephone during normal
business hours. We will still provide support on questions of API usage,
licensing, and deployment... Including moving licenses to new machines. If you
run into a bug/issue, support will work with you to se if there's a workaround
available or if the issue was addressed before the final 10.7.0.13 build.. If
the bug /issue was resolved in 10.7.0.13 or before we can assist you to update
to a version with the fix.
If support determines that the issue was not
fixed until /after the 188.8.131.52 initial release.. or if your issue requires a
code change to DotImage, the fix can not be and will not be back-ported to an
older version.. the fix would be provided in a new 11.0 (or later) build and you
would need to upgrade your solution to 11.0 (or newer) to receive the fix. This
is non-negotiable as we are contractually forbidden from providing any "new"
10.7 or older build using the old PdfReader.
Q: How difficult is it to upgrade to 11.0?
A: To a large extent, this depends on what version you're
Mostly you just need to ensure you're targeting .NET 3.5 or .NET 4.5.2 or
higher, change your Atalasoft DLL references to point to the correct 11.0
versions, and activate your licenses for 11.0.. There are some other changes in
11.0 which are detailed here.
We try very hard to introduce as few "breaking changes" and API / code
changes in new releases as possible. There are certain key milestones within
DotImage where various individual components did introduce significant
v5.0 - Compete re-write of Annotation code - significant
changes to go from 4.0 or lower to 5.0 or higher
v6.0 - Last version of DotImage to include support for .NET 1.1
v7.0b - Entirely new Barcode Reader engine and API introduced - users with
Barcode reading solutions from 7.0a and older will have significant code
INFO: Barcode Reader Basics (DotImage 7.0b thorugh DotImage 9.0d)
v10.0 - Barcode reader engine changed again, but only namespace and licensing
and dll reference change... no API / code changes beyond namespace change
v10.3 - Major Assembly restructuring - several dlls removed from DotImage..
features moved into other DLLs - no major code changes.
INFO: AssemblyRestructuring Introduced In Version 10.3
v10.5.2 - Complete architecture change For WingScan web scanning - No more
browser plugins. No customer can / should be using WingScan with any version
priori to 10.5.2 at this point.
Q10408 - HOWTO:
Migrating a WingScan based app to 10.5.2 (and newer - includes 10.6, 10.7 and
v10.6 - Significant changes/improvements to WebDocumentViewer control -
STRONGLY recommended to not use any version before 10.6.1 for
v10.7 - Several minor, but well documented changes.
Q10436 - INFO: Changes
Introduced in 10.7
v11.0 - PdfReader changed from old engine to Pdfium. No Code changed
required, but license change means new PRP2 serials must be used instead of PRS2
serials. Also, dropped support for .NET 2.0/3.0 and dropped support for .NET
4.0/4.5/4.5.1 - use .NET 3.5 or 4.5.2 or higher.
Q10443 - INFO: Changes
Introduced in DotImage 11.0
For assistance / questions regarding upgrading to 11.0, please create a
support case or call in to support.
Q: Why can't you sell / provide a new PRS2/ PRSX2 serial so
we don't have to upgrade?
A: Once our business relationship with Foxit ended, our
contractual agreements require that we can never sell / provide any new licenses
for the old PdfReader. To do so would be to violate Foxit's copyright /
licensing. There is no "wiggle room" on this one. If you do not have all the
PRS2/PRSX2 serials you need to properly develop and deploy your 10.7 and older
needs, the only path forward would be to move to 11.0 or later to use the
PRP2/PRPX2 serials. Support can assist with technical questions/issues arising
from upgrading, though the vast majority of customers upgrading to 11.0 or later
have had little to no issues doing so. Those who have had any difficulties have
reached out to support and we've assisted them.
Q: Any other questions...
