Our development process includes several applications that use the UI for WinForms. As such, we will download the latest release and evaluate all of our applications against it prior to updating all of our developers and our build servers. However, using the Control Panel does not provide any option for maintaining the previous install, so whichever developers are doing the evaluation have to manually reinstall the prior version, or manually install the new version, in order to be able to roll back if we decide not to adopt the latest release. Please add an option in the control panel to maintain the previous version when installing updates.
