Installation notes

If you are reinstalling or updating ThumbsPlus, you should use the same installation type that you used previously to avoid losing your preferences and customizations. When using the Everything in one folder installation type, you should also use the same installation folder.

Note that major version upgrades (i.e., version 8 to version 9) always reset your preferences because there are many preference changes that may be incompatible between versions, and because they are stored in different files, so that you can install a later version to evaluate without resetting your installed version's preferences.

If you use the old-style Everything in one folder installation option, be sure to install to a folder that does not require UAC (user access control). Most importantly, do not install in the C:\Windows, C:\Program Files or C:\Program Files (x86) folders (or their equivalents in your language).

When installing Everything in one folder on your system drive (usually C:), we recommend installing in a sub-folder of the application common data folder, which is usually C:\Programdata. Thus the recommended destination is C:\ProgramData\ThumbsPlus. Because the common data folder does not properly exist on Windows XP, the recommended destianation is C:\ThumbsPlus9.

When updating, the installer will uninstall any prior version 9 build. However, the installer does not uninstall version 8 or earlier. Once you no longer need it, you can uninstall the prior version from Control Panel.

If you encounter problems during the installation, please send us the Thumbs9Install.log from your user TEMP folder along with your problem report. (If you're not sure where this is, hit Win+R, enter %TEMP%, and hit enter, and Explorer will open it for you). The Win key has the Windows logo (Win logo) and is usually between the Ctrl and Alt keys. If your keyboard doesn't have one, consult the documentation for your keyboard and version of windows, or run the command START %TEMP% from a command prompt. Send this file to, and be sure to provide a meaningful email subject (such as "Unable to install ThumbsPlus 9 build 3935").


All single-user and home network users who ordered or upgraded ThumbsPlus on or after 15 January 2012 received version 9 at no additional charge.

Concurrent license users who are up-to-date with their annual support contracts have received version 9 automatically and at no additional charge. Those with out-of-date support contracts may upgrade at $50.00 per user.

If you are eligible and did not receive your version 9 code, please contact the order desk.

Major new features

There are many improvements and additions to the Python scripting capabilities. We're working on sample scripts that will be included with version 9, and will announce them on the forums as they become available. See the section below on Python scripting for more info.

Several of the new features in ThumbsPlus 9 depend on Python (including Facebook access),, and in the future we will be moving more and more high-level functions to Python. Of course, the core image processing, database, and many other internal functions will remain written in C++ and C (and even a bit of assembly language for some important speed optimizations).

We're looking forward to see what kinds of functions our users can contribute as well!

  • Fixed the toolbar Thumbnail - Scan Folder button.
  • Added crash information to Subject when emailing a crash report (for ease in tracking specific crashes).
  • Column headers were displayed incorrectly in the thumbnail pane when display of thumbnails disabled.
  • Fixed problem of display in the file filter drop-down on thumbnail pane.
  • Worked around the problem in which Windows tried to load runtime libraries from invalid locations (runtime error R6034 and hanging on startup)
  • Resets the 30-day evaluation period. If you evaluated any prior version 9 build and found it lacking, please try build 3928 as there are a lot of fixes and improvements!

  • Fixed crash when trying to make a thumbnail with F3 and no files were selected.
  • Fixed problem using evaluation version with client/server databases.
  • Fixed a problem that could cause crashes or skipped files and folders when recursively processing folder trees, including Print Catalog, Contact Sheets, Web Page Wizard, and in some cases Thumbnail Tree.

  • Improved error logging and crash handling.
  • Fixed tree display of folders containing pound signs (#).
  • Vast improvement to speed of removing orphans (Thumbnail - Remove - Orphans).
  • Removed button to create folder share as it was not working properly. (Use Windows Explorer instead.)
  • Many additional small bug fixes and minor improvements.

These issues required work in the depths of the code mine (and rewriting a ton of really old code), that is not all that visible, but took several design and programming weeks. Getting these out of the way first helps the more visible fixes and changes to procede at much faster pace.

  • Removed many possible buffer overruns throughout ThumbsPlus
  • Likewise, fixed dozens of (individually unlikely but collectively more common) crashes due to poor or outdated string and memory handling, stack usage, and null pointer accesses

  • Improved crash handling and reporting
  • Provided a checkbox in ThumbsBug to indicate whether a screen shot should accompany the bug report

  • Fixes to gallery handling
  • Added query to save gallery order when leaving a gallery

When using the Everything in one folder installation type, you should also use the same installation folder. See the Installation Notes for more information on Everything in one folder installation.

  • Several fixes and improvements to JPEG processing
  • Improved handling of default font, so that XP can get Arial (yuck) while later OSes get Segoe UI

Known problems remaining

There are several other issues remaining; please use the forums, where I am spending a lot more time, to submit and discuss problems that haven't been addressed, or to request minor enhancements.

Known Facebook issues

There are a couple of Facebook problems I've spent time on but not completed yet:

  • ThumbsPlus only retrieves the first 25 images in an album
  • Images are not retrieved at full size
  • The facebook cache becomes too large

ThumbsPlus caches facebook query results internally, and compresses, saves and restores them between sessions. This can take a lot of memory, so I will be changing the cache so it uses a local disk file instead. This will also eliminate the time required to load and save the cache. The cache file is called Thumbs9.fbcache and is located in your preferences folder, which you can open from Start menu - All Programs - ThumbsPlus - Utilities - View Preferences Folder.

Downloaded files are cached in a subfolder of your TEMP folder (%TEMP%\Tp_Fb). This cache is not currently pruned. You can remove all of the files anytime; ThumbsPlus will re-download them if you make thumbnails or view them.

The Keep me logged in to ThumbsPlus option on the Facebook login window does not work when restarting ThumbsPlus.

Using Python for scripting and customizing ThumbsPlus 9

Information on scripting is now in the help file.
