Windows Media Player 5.2

Windows Media Player 5.2 is a version of Windows Media Player. It is technically NetShow Player 3.5, as it was developed upon it. While a final build was released for Windows 95, Windows NT 4.0 and the original release of Windows 98, only a beta build was released for Windows 3.1x, with support for it being dropped in the final release. Installing on Windows 3.1x requires the TCP/IP protocol to be installed first, otherwise it will crash due to  being missing. It will also install the Video for Windows runtime and additional codecs.

It is included on the installation media of Windows NT 4.0 SP4.

Quirks
As being a beta release, it still bears the older NetShow Player branding in some places.
