As RealNetworks makes new products available to customers, it is not possible to continue supporting legacy and historic products. For more information, see: https://customer.real.com/hc/en-us/articles/204039423
We always recommend using the latest version of RealPlayer - RealPlayer 18/RealTimes, as it is continuously being updated and it's compatible with the current operating systems. Unfortunately, it is not compatible with Windows Vista and XP. We do not guarantee reliability of the older products and some features, such as the Download feature may not work properly. Also, we do not offer any updates for old versions.
