Uninstalling IMatch 2015 after installing IMatch 2017

If you install IMatch 2017, it automatically migrates all IMatch 5 settings, presets and other data. This allows you to run IMatch 5 and IMatch 2017 side-by-side, e.g., while you are testing things or migrate your scripts.

Uninstalling IMatch 5 After Installing IMatch 2017

When you’re ready to switch to IMatch 2017, you can uninstall IMatch 5 using the standard Windows uninstall process: Windows control panel > Add/Remove Software.

Windows will not delete the %PROGRAMDATA%\photools.com\IMatch5 and %APPDATA%\photools.com\IMatch5 folder hierarchies when uninstalling IMatch 5. This is usually a good thing, because it keeps all your settings, custom presets and templates in place when you have to reinstall IMatch for whatever reason.


Some special Windows folders are named differently by different Windows versions. We use here the corresponding environment variables %PROGRAMDATA% (all users and applications) and %APPDATA% (per-user data) to refer to these folders. Usually they resolve to:

%PROGRAMDATA%: C:\ProgramData
%APPDATA%: C:\Users\YOUR-USER-NAME\AppData\Roaming

Deleting the Folders Manually

There is not really a need to do this, but if you are a tidy person and you want to free some disk space, you can delete the IMatch 5 folders in Windows Explorer. Delete

%PROGRAMDATA%\photools.com\IMatch5 and %APPDATA%\photools.com\IMatch5.

Before You Delete…

Open Edit > Preferences > Application in IMatch and check that all folder options use the imatch6 and not the imatch5 folders:

  • Presets Folder
  • Dictionary Folder
  • User Dictionary Folder

In Edit > Preferences > Cache also check the location of the IMatch preview cache folder.

The Preview Cache Folder

When migrating settings from IMatch 5 to IMatch 2017, IMatch does not move or duplicate the preview cache folder. This would waste a lot of disk space and take a long time. Instead, it keeps the original cache folder location, which is by default %PROGRAMDATA%\photools.com\IMatch5\previewcache.

If you want to remove the IMatch5 folders, move the preview cache folder from …IMatch5\previewcache to …IMatch6\previewcache and update the corresponding setting in Edit > Preferences > Cache:

Early IMatch 2017 Installer Fix

The very early IMatch 2017 installers (2017.5.4 and below) accidentally duplicated the preview cache folder on some computers. We’re sorry.

If you did install IMatch 2017 with one of these installers, can check if both %PROGRAMDATA%\photools.com\IMatch5\previewcache and %PROGRAMDATA%\photools.com\IMatch6\previewcache contain files and sub-folders.

Check which of these folders is used by IMatch 2017 under Edit > Preferences > Cache. Then clear the contents of the other folder to reclaim disk space (keep the previewcache folder, just delete its contents).
