Created a video and saved it in a .wlmp and a mp4 file format. I can not share via email or facebook, but I can open it in Windows media player. Reading in  this forum I have checked .Net Framework 4.5, have used the Fixt Tool. Have also followed suggestions  to use MedioInfo and  run codecs converters. MediaInfo was flagged as unsafe for my computer and because of the codecs convertor I now have an add-on from Jollywallet which I can not get un-installed.  Using Windows 7.
