I understand how this can be confusing but you don’t have to worry since you have the correct versions of MSN (10.20.0091.1100) and Internet Explorer (8). The MSN butterfly’s backbone is Internet Explorer.

The reason why there is a discrepancy of how the other websites detect what version of MSN or Internet Explorer you have can be found on this link: http://msdn.microsoft.com/en-us/library/ms537503(VS.85).aspx

Feel free to reply to this post for any questions and feedback.

Thanks!
