All Mapsoft Plugins Now Available for 64-bit Adobe Acrobat
Our complete product range now supports both 32-bit and 64-bit Adobe Acrobat, keeping you covered whichever version you run.
We are pleased to announce that all Mapsoft Adobe Acrobat plugins have been updated with 64-bit support. As Adobe continues its transition towards 64-bit Acrobat, we have ensured that our entire product range is ready — while continuing to support 32-bit Acrobat installations for customers who have not yet migrated. This update follows the initial 64-bit release of TOCBuilder, which was our first plug-in to make the transition and served as the template for the rest of the suite.
Products with both 32-bit and 64-bit support
The following 13 products now ship with both 32-bit and 64-bit versions. Each installer automatically detects your Acrobat installation and installs the correct version:
- Bookmarker — PDF bookmark creation
- TOCBuilder — Table of contents generation
- MaskIt — Content redaction and removal
- DogEars — Page tabs and navigation
- Impress — Text stamping and watermarks
- Impress Pro — Advanced stamping with batch processing
- Flattener — Annotation and form field flattening
- MediaSizer — Page size management
- ContentScaler — Content scaling and repositioning
- ImagePlacer — Image placement and watermarking
- FDA Checker — FDA compliance checking
- SecuritySetter — PDF security and encryption
- InfoSetter — Document metadata management
64-bit only products
The following products are built exclusively for 64-bit Adobe Acrobat DC:
- Check PDF Standards — PDF standards compliance detection (free)
- Engage — Mail merge and variable data printing
Why 64-bit matters
Adobe has been progressively moving Acrobat to 64-bit, and automatic updates are now migrating many users from 32-bit to 64-bit Acrobat DC. The 64-bit version offers improved performance and the ability to work with larger documents by accessing more system memory. Mapsoft products are built as native Adobe Acrobat plugins using the Acrobat SDK, which requires recompilation for each target architecture. A 64-bit Acrobat process cannot load a 32-bit plug-in DLL — the two architectures are incompatible at the binary level — so every plug-in in the suite needed to be rebuilt, tested, and packaged separately for each target.
If you are unsure which version of Acrobat you have installed, check the title bar — Adobe displays either (32-bit) or (64-bit) after the application name.
What the Update Required
Moving the full plug-in suite to 64-bit was not simply a matter of recompiling with a different target flag. Each plug-in had to be audited for pointer size assumptions, integer type casts, and any dependencies on third-party libraries that needed 64-bit builds. Across thirteen plug-ins plus the two 64-bit-only products, this represented a significant amount of work — particularly in areas of the codebase that had been written years earlier and reflected the assumptions of a 32-bit world.
Some of the more intricate work involved plug-ins that write and read preference files or communicate with external processes. On 64-bit Acrobat with Enhanced Security enabled, file system access behaviour can differ from 32-bit Acrobat, and we encountered edge cases that required careful handling to ensure preferences saved by the 32-bit version were still readable by the 64-bit version. Existing customers upgrading from 32-bit to 64-bit Acrobat should not notice any difference in behaviour, but ensuring that backwards compatibility under the hood required deliberate testing.
Testing across Acrobat versions is a recurring challenge for any third-party plug-in developer. Adobe releases Acrobat updates on a regular cadence, and each update can introduce subtle changes in SDK behaviour or Enhanced Security policy. We maintain a test environment covering the current Acrobat DC version alongside recent previous releases, and the 64-bit update was validated across this matrix before release. Plug-ins were tested against representative documents of varying sizes and complexity — from simple single-page PDFs through to large, heavily bookmarked technical manuals — to verify that the 64-bit builds produced identical output to the 32-bit versions.
Products Discontinued During the Transition
The 64-bit update was an appropriate moment to review the full product range and make decisions about products that were no longer commercially viable to maintain. A small number of older products that had limited uptake and significant maintenance overhead were discontinued rather than ported to 64-bit. This is a pragmatic reality for any software business: maintaining a product for an architecture transition costs real development time, and that time has to be justified by the product's user base and revenue. Discontinued products continue to function for customers on 32-bit Acrobat with perpetual licences, but will not receive further updates.
The products that remain in the active catalogue — the thirteen listed above with dual 32/64-bit support, plus Check PDF Standards and Engage as 64-bit-only — represent the core of what our customers use day-to-day. We are committed to keeping these products current with Acrobat releases going forward, which is one of the reasons we have moved towards annual subscription licensing alongside the perpetual licence option.
Automatic detection
You do not need to choose between 32-bit and 64-bit versions when downloading. Every installer automatically detects your Acrobat installation and installs the correct plugin version. If you later upgrade from 32-bit to 64-bit Acrobat, simply re-run the installer and it will install the 64-bit version using your existing licence key.
Download the latest versions
Updated installers for all products are available now from our products page. Existing customers with a valid licence can download and install the update at no additional cost. If you have any questions about whether a specific product version is compatible with your Acrobat installation, the support page has version compatibility information, and our team is happy to advise directly.
