Database opening failed

    Hi Nigel,

    Hmm, let's make it work for you. Please do the following to get Luminar up and running:

    1. Make sure Luminar is closed.
    2. Locate your Luminar 4 Catalog folder. The default location is C:\Users\%username%\Pictures\. If you specified a custom location for your catalog, search your custom location.
    3. Rename the Luminar 4 Catalog folder. Choose any name you like. Don't remove this folder.
    4. Press the Windows logo key + R.
    5. Type %appdata%\Luminar 4 in the dialog box that opens and press Enter on your keyboard.
    6. Next, remove all the contents in Luminar 4 folder you opened in Step 5. Please note that this will remove your user looks and workspaces, so back up the folder into the safe location before removing it if necessary. You can then put your looks and workspaces back later.
    7. Start Luminar. It will ask you to complete the initial setup. While performing the setup, leave the location of the catalog at the default.
    8. When Luminar has loaded, click File > Catalog > Open > navigate inside the folder you renamed in Step 3 > double-click Luminar 4 Catalog.luminar file. Your previous catalog should load.

    Please note: File > Catalog > Open is for opening catalog files, not photos. If you try to open a photo like this, you will receive a Database Opening Failed error.

    If you'd need more assistance on this, please, reach us at and we'll do our best to make it up and running for you.

    It doesn't work for me. The app creates the contents again and the same failure dialogue box comes up.
