Help! My Data Visualization Desktop Maps Stopped Working!

Twice in the past 2 days, I have had coworkers reach out because their maps in Oracle Data Visualization Desktop stopped rendering. When they switched the visualization away from a map, a visualization would show. Likewise, when they exported a project (.dva) and sent it to a coworker for testing, it worked for the recipient. What we found was that both people ran a Disk Cleanup on their machine recently. It seems that Disk Cleanup deletes some necessary files (presumably from a temp directory) for map rendering for DVD. If this has happened to you, here are the steps to fix DVD and maps:

  1. First see if you can export the project (.dva), delete the project from DVD, then reimport into DVD. If it works, then you are good to go! If not,…
  2. Make sure you export each of your projects that you want to save.
  3. Uninstall DVD.
  4. Delete the following folder from your machine: C:\Users\{username}\AppData\Local\DVDesktop (yes, the whole folder!)
  5. Reinstall DVD (reinstall Advanced Analytics if desired)
  6. Import your projects.

You should be good to go!
