Guide: If there is a Reolink Client installed on your computer already, but you want to install another Reolink Client with an old version on your computer, please check whether the version of the already existed Reolink Client is newer than the version that you are trying to install. If it is, please uninstall the newer version and then install the old version. In this way, we can avoid the possibility that some features will be unavailable in the old version Reolink Client.
