RC1 – External Players not detected

Whereas SMPC on the same Device, with the same “playercorefactory.xml” can detect MxPlayer, Kodi 17RC1 fails to detect any player.
“playercorefactory.xml”:

Code:
<playercorefactory>
        <players>
                <player name="MXPlayerFree" type="ExternalPlayer" audio="false" video="true">
                        <filename>com.mxtech.videoplayer.ad</filename>
                        <hidexbmc>true</hidexbmc>
                        <playcountminimumtime>120</playcountminimumtime>
                </player>

        </players>
        <rules action="prepend">
<!---

-->
                <rule protocols="smb" player="MXPlayerFree" />
                <rule dvdimage="true" player="MXPlayerFree"/>
                <rule protocols="rtmp" player="MXPlayerFree"/>
                <rule protocols="rtsp" player="MXPlayerFree" />
                <rule protocols="sop" player="MXPlayerFree" />
                <rule internetstream="true" player="MXPlayerFree" />
                <rule video="true" player="MXPlayerFree"/> <!-- Default for anything else not listed -->
        </rules>
</playercorefactory>
