For recent versions of Dameware, there are no specific instructions for upgrading Dameware. You can install a new version of Dameware over an older version of Dameware. The installer of the new version of Dameware uninstalls the old version of Dameware for you.
SolarWinds strongly recommends that upgrades be performed using the same admin account from the previous installation.
However, if the automatic uninstallation does not work for any reason, refer to the following Success Center article for instructions to manually uninstall Dameware before upgrading to a newer version: Manually uninstall Dameware Remote Support and Mini Remote Control from a machine.
