Before you can deploy this version of Rumba, you must uninstall any previous versions of Rumba that are currently installed.
The easiest way to uninstall Rumba varies according to the version of SCCM you have installed. In some versions of SCCM the easiest way to uninstall previous versions of Rumba is to include a response file (response.ini) or definition file (.pdf) in a command line as part of an uninstallation deployment package. In this case, if you do not have the previous-version documentation and the .pdf or response file (or files) of your previous Rumba installation, you must create a new response file.
In other versions of SCCM, the easiest method is to create a task sequence to run the uninstallation. Refer to the documentation for your SCCM version.
