Luminar will not start

    Please try creating a new Luminar Catalog:

    1. Make sure Luminar is closed.
    2. Locate your Luminar 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 Catalog folder. Choose any name you like.

    Note that the albums you created in Luminar and edits you made will not be accessible in Luminar after you've renamed the catalog folder. They will still be saved on your hard drive should you need to access them in the future. Your photos on disk won't be affected in any way.

    After that, you should be able to create a new catalog. 

    Please load your photos in parts so Luminar don't freeze. Don't add the whole drive.


    If this doesn't help, please send us event logs:

    1. Reproduce the issue.
    2. Press the Windows logo key + R.
    3. Type eventvwr in the dialog box that opens and hit Enter on your keyboard.
    4. In the window that opens click the triangle next to Windows Logs on the left. A directory tree should open.
    5. Click Application in the directory tree. 
    6. In the main part of the window find the two topmost entries marked with Error named Application Error and .NET Runtime.
    7. Hold CTRL and click your left mouse button on each entry to select them both.
    8. Right-click on any of the two selected entries and click Save Selected Events.
    9. Name the file, save it, and send it to

    Looking forward to hearing from you.
