When you originally purchased RealPlayer Plus, you purchased RealPlayer 16, which was a one-time charge. Each version (RealPlayer 18, RealPlayer 16, RealPlayer 15, etc.) is considered a separate product--so with that purchase, you received updates and support of that version for no additional fees or hidden charges. However, we are no longer updating or supporting that version.
For customers on Windows 7 and higher, we are now offering RealPlayer Plus version 18. This product offers additional features not included in previous versions. If you want RealPlayer Plus version 18 with the additional features, it requires a purchase.
