DW Spectrum Clean Uninstall (Windows & Ubuntu)

When DW Spectrum is uninstalled, the default behavior of the software is to leave behind data regarding the user's preferences. As a result, when the DW Spectrum Server component is reinstalled, the previous settings will remain. This can be an issue if you intend to perform a clean re-installation of DW Spectrum or must delete all DW Spectrum data from the Server’s host computer.

This article will guide you through how to completely remove all DW Spectrum Server files.  Please follow the steps below to delete any DW Spectrum remnants from your machine.

 

**NOTE:  If you are trying to replace the DW Spectrum Application Bundle version with the individual Client and Server software components, you can refer to the article “DW Spectrum – Bundle Replacement Procedure”.

**NOTE:  If any recording licenses were registered for the DW Spectrum System on the computer, make sure to deactivate the registered licenses before removing DW Spectrum from the computer.

 

Create a Database Backup
