Excire Search: Questions about installation, registration and menu entries

To install, simply use the downloaded installers for the various platforms. These will guide you comfortably through the installation. After successful installation, you will find a new entry, “Excire Search” in your Lightroom add-on module manager. You can access this via the menu “File -> Add-on module manager”.

To uninstall Excire Search from your computer, proceed as follows:


Re-open the Excire Search installation disk image and double-click “Uninstall.“.
The latest installation disk image can be found here..


Open the Windows Control Panel and select“Programs”and then“Programs and Features.”Search forExcire Searchin the list of installed programs and select“Uninstall".

On macOS, the most common cause of a failed installation is that Excire Search was either manually moved after a previous installation, or Excire Search was copied from a backup program to another location.

In both cases, the subsequent update cannot be installed. The failed installation may also cause an error when subsequently launching Lightroom.

How to fix the problem is described here. .

During the installation, any location can be chosen on Windows for the installation. The default path is “C:\Program Files/Excire Search”. On Mac OSX, only the default path (“/Applications/Excire Search”) is possible. Excire Search consists of the Lightroom plugin (excire-search.lrplugin) and a background program. Both are located in the installation directory.

After installation, the program must not be moved to another location.

If the program has been moved, then a later uninstall cannot be done correctly. A later installation of a newer version after a move will result in only the Lightroom plugin being updated, but not the background program.

As a result, Excire Search no longer starts. The error message “Excire Search was not installed correctly. Please reinstall Excire Search.” Contrary to the error message, however, reinstalling does not fix the error.

Fixing the problem:

The problem can only be fixed by either moving Excire Search from its new location back to its default location or (Mac OSX only) deleting it here. This has to be done manually. Then the latest version (see announcements) can be reinstalled.

If you can’t remember where you moved Excire Search to, you can open Terminal on Mac OSX and copy the following command into it:

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -dump | grep –only-matching “/.*/excire-search.app “

This should output the path to Excire Search. Any copies that are not in the original installation location (see above) must be deleted for the installation to work again. Alternatively, on both operating systems, you can, of course, use the file manager search (Windows Explorer / Finder).

You simply enter your license key in the “Excire Search” section in the Lightroom add-on module manager. You can access this via “File → Add-on module manager”.

To initialize your photos, go to “Libary → Add-on Module Options → “Initialize Photos…”in the menu. Please note that these entries are located under “Library” and not “File”.

In Lightroom, there are several entries called Additional Module Options. Excire Search can be found under “Library → Additional Module Options”..

Typically, Excire Search is registered as an add-on module in Lightroom during installation. In Lightroom’s Add-on Module Manager, Excire Search is in the list of add-on modules.

However, in rare cases, this fails. Also, when you update Lightroom, Excire Search may be removed from this list.

To manually add Excire Search as an add-on module in Lightroom, follow these steps:

  1. Go to Lightroom’s Add-on Module Manager(File → Add-on module manager),).
  2. Click on"add"(bottom left).
  3. Select the following folder:

Mac: „/Applications/Excire Search/excire-search.lrplugin“

Windows: „C:\Programme\Excire Search\excire-search.lrplugin“

Excire Search: Questions about Excire databases and Lightroom Classic catalog

Our Excire Search database file is located in the same directory as the corresponding Lightroom catalog, has the same name, and ends with “Excire.excat”, e.g. a catalog “xxx .lrcat” has the Excire Search database “xxx Excire.excat”. Please note the space before the string “Excire”.

Excire Search stores the initialized photos’ data in a separate database, which is located next to the Lightroom catalog. A backup of this database is automatically performed before and during each significant initialization. The backup is also located next to the Lightroom catalog.

Excire Search stores the initialized photos’ data in a separate database, which is located next to the Lightroom catalog. A backup of this database is automatically performed before and during each significant initialization. The backup is also located next to the Lightroom catalog.

The Excire Search database and the backup both have the Lightroom catalog’s name, but also have the extensions “Excire.excat” and “Excire.excat.bak” respectively.

When performing a backup of the Lightroom catalog, it is copied to a separate backup folder. By default, this is a subfolder called “Backups”. However, the Excire Search database will not be copied. If such a backup is opened directly, Excire Search will not find its own database, as it expects the database to be next to the catalog.

In this case, Excire Search issues a corresponding message and creates a new, empty database next to the catalog backup. Therefore, we recommend copying the Excire Search database next to the Lightroom catalog backup before opening a backup directly.

Alternatively, to restore a Lightroom catalog, the backup can be copied to the catalog’s original directory, replacing the current catalog with the backed-up catalog.

Since the Excire Search database is already in that directory, it can now be used seamlessly with the restored catalog.

In rare cases, it may be necessary to reset the Excire Search database or restore from a backup.

Proceed as follows:

  1. Go to Lightroom’s Add-on Module Manager(File → Add-on module manager),and select “Excire Search.”
  2. Click on the“Reset or Restore Database…” button on the right-hand side..
  3. Select whether you want to reset the database or restore a backup (if one exists).

After resetting the Excire Search database, all photos must be reinitialized.

The Excire Search database is always located in the same folder as the Lightroom catalog. For example, if the folder with the Lightroom catalog is copied to a network drive and opened from another computer, Excire Search will also open the corresponding database.

However, using the database from multiple computers at the same time is not possible. Only using it one after the other works.

Note that storing the database, including the previews, on a network drive may impact performance.

However, one license may be used on up to three computers.

In addition to the Lightroom catalog, simply copy the Excire Search database file to the appropriate destination directory. The Excire Search database file is located in the same directory as the corresponding Lightroom catalog, has the same name, and ends with “Excire.excat”.

Searching across multiple catalogs is not possible because Lightroom strictly separates the catalogs. To search for all your photos, create a master catalog into which you import all your photos.

Excire Search: Questions about functionality

To initialize your photos, go to Library → Add-on Module Options → “Initialize Photos…”..

The function“Reinitialize photos…”should be called whenever an image or several images have been edited significantly. Then the mathematical representations are recalculated to fit the current images. Especially if an image section or the image colors have been strongly altered.

In the case of the latter, however, you should first deactivate the“Fast initialization”option in the “Excire Search” section of the add-on module manager.

The duration of initialization depends on several factors. The number of images in the catalog, the number of processed images, the image resolution, and the storage location all affect the runtime. If necessary, the initialization can be interrupted at any time and resumed at a later time.

The “Excire Search – Initialize Photos” dialog also offers the selection option “Maximum CPU usage”. This selection is recommended if the computer is not used for other tasks besides initialization.

Furthermore, there is the by default activated function “Fast initialization” in the add-on module manager. This function has the effect that edited photos are not exported.

In addition, the runtime can be reduced by using an SSD hard disk.

An automatic initialization can be activated or deactivated in the plugin settings in the additional module manager.

Excire Search supports many image formats, including various RAW formats. However, some very new formats are not supported by Excire Search, although you can import these photos into Lightroom.

In these cases, Excire Search automatically performs an export during the initialization of these photos, creating a JPG in a temporary folder. This JPG is used for initialization and then deleted.

When searching, you have the option to disable the“Overwrite previous results”option. If this option is disabled, the search results will no longer be displayed in the “Excire Search” collection.

Instead, a new collection is created for each search. This allows you to keep the results from previous searches.

Alternatively, you can copy the photos from a results collection into a new collection to save the search results. Be sure to set the new collection’s sort order to“Custom Order”as well, so that the search results are sorted according to the search.

If Excire Search shows you an error that occurred, you can send us a bug report by clicking onin the “Log files” section..

You can also send us a bug report after an error has occurred by selecting “Excire Search” on the left side in the add-on module manager(File → Add-on module manager),scrolling down on the right side, and clicking on“Send bug report…”in thein the “Log files” section..

If you do not have access to the menu, you can find the log files under:

Mac: ~/Library/Logs/excire-search

Windows: %appdata%\Excire Search\Logs

 These are all files with the extension “.log”. Send them to support@excire.com with a brief description of the error.

On Mac OSX, the easiest way to find to the location of the log files is to select “Go to” → “Go to folder” from the Finder menu. On Windows, you can click in the address bar in Windows Explorer and type or copy the path there.
