Comment 23 for bug 1164453

This worked for me:

1. Open your file manager and go into your Home folder.
2. Make hidden files and folders visible.
3. You should now be able to see the ".wine-browser" folder. Make a backup copy of it just in case Murphy's law comes into play.
4. Delete the ".wine-browser" folder completely--the entire thing, "drive_c" folder and all. No software or vital system files will actually be lost.
5. Restart Netflix Desktop. Wine will detect the absence of the ".wine-browser" directory, quickly recreate and rebuild it, and then promptly open Netflix Desktop. The Silverlight update issue should then be resolved.
6. You may not run into this last issue (bug #1104373, sound but no video), but I did. After I made it past the Silverlight update roadblock, I heard the movie playing but the screen was black. All I did was estimate where the play/pause button would be on the screen and clicked on that spot twice. Boom...picture back.
7. Once you are satisfied that everything is functioning normally, don't forget to delete the temporary backup of the ".wine-browser" folder created in Step 3.
