Cause


This is a different presentation of an issue that can arise when a user's Windows password is changed. The cause is the same as described in "An Unhandled Exception Occurred" when opening Manage Data Connections window :  

The GalleryAlias.xml file is corrupted or the file cannot be decrypted.

Resolution


  1. Close Designer
  2. In File Explorer, navigate to %APPDATA%\Alteryx\Engine
    1. The actual path will vary, but it will take the following form: C:\Users\your_username\AppData\Roaming\Alteryx\Engine
  3. Delete the GalleryAlias.xml file (or rename it so that Alteryx will not find it and then after resolving the issue delete the renamed file).idea Skyscrapers
  4. Restart Designer.
