How to 'reauthorise' and 'locate' in the Spitfire App

Last updated:


If you have a red exclamation mark in the top left of your Hans Zimmer Strings interface, or a "missing presets/samples" error in BT Phobos, you will likely need to perform a reauthorise and locate using the Spitfire Audio App.


Using the 'Locate' feature

1. Open and login to your Spitfire Audio App and navigate to the product you intend to reauthorise. If you do not have the App on your PC, you can download it here.


2. You will see a small cog icon HZArticle_Cog.png, select this and from the dropdown choose "locate". If you do not see this option and instead see "reauthorise" it is likely that your library has an update available, and it would be recommended to download this first.


3. You will be presented with a new page asking you to select the location of the library. For the sake of this example, I will be locating Hans Zimmer Strings. When locating, it is important that you browse to the exact folder that the library is located in. By default, the library folders would be named:


BT Phobos: "Spitfire BT Phobos library"

Hans Zimmer Strings: "Spitfire Audio - Hans Zimmer Strings"

Note: If you have renamed these folders for any reason, it is highly recommended to rename these to the above.


Once you are confident that you have selected the correct location, press "locate". This will rewrite your file, and direct the application to the correct path.



4. After completing this step it is a good idea to close the App and check to see if the issue is fixed. In some cases a simple rewrite of your will resolve the issue. If you are still having an error message, you may also need to reauthorise.


Using the 'Reauthorise' feature

1. Re-authorising is very similar in process to locating, however the option will not appear unless the library is reset in the App. If this is the case, you'll need to reset it.


2. To reset a library, navigate to the product you wish to reauthorise and select the cog HZArticle_Cog.png and choose "reset". A screen will ask if you would like to reset the whole library or just the "latest update". Whilst the selection on the whole does not matter, I would recommend selecting latest update.


3. After resetting, it's likely you'll need to refresh the App. You can do this by selecting the cog at the top of the window and choosing "refresh", or you can simply close and reopen the App.


4. You'll know that you've reset the library correctly when it shows as available to download. From here, you'll need to once more select the cog on the appropriate product page. This time choosing "reauthorise".


5. A new screen will ask you to specify the location of your library. Similar to locating, this folder will need to be named correctly. Once you've done this, select "reauthorise" and a small download will begin. This will download new Presets and Patches, as well as the necessary plugin files to their default locations. 



6. Once completed, open your DAW and load the instrument. If done correctly, the issue should now be fixed.
