I have just had the same problem in Windows Vista Ultimate.
I solved the issue by simply using WinRar to unzip the Zip folder.
I installed WinRar and then right clicked on the Zip Folder, clicked
Oopen With... Then I browsed to c:\program files/winrar/winrar.exe
and then selected Winrar from the list of programs when it appeared!
It then unzipped with no problems!
Winrar is avalibale free from Download.com
Hope this helps!
