To install additional features or reinstall an existing feature once an initial installation of Sybase WorkSpace is complete, re-run the installer.
You do not need to uninstall Sybase WorkSpace because the installer detects the existing installation location and automatically displays the feature selection page in the wizard.
The installer does not allow multiple installations of Sybase WorkSpace 2.5 on the same machine. You can have different versions of WorkSpace installed on the same machine, but not multiple installations of the same version.
