Yeah, it's a known "zip extracting tool problem", or call it a feature.
If you use tools like WinZip or Winrar etc. they will create a new folder by the name of the zip archive if you "just extract" the files.
Either open teh zip and click the folder in there (the addon's/lib's folder) and only extract this to your live/AddOns folder,
or maybe use the addon manager Minion.
It will help you to download, extract and, what is important!, update your addons and libraries:

For Minion related questions and problems please READ the minion troubleshooting thread BEFORE downloading it!
There are some infos in there like udownload the 32bit version even if you sue a 64bit operating system,
and infos about whitelisting minion and your live/addons folder in your antivirus tool/windows defender:
