installing blender 2.5 :(

Hello,
I have downloaded blender 2.5 for 32bit windows from
http://www.blender.org/index.php?id=1262&f=http://download.blender.org/release//Blender2.50alpha/blender-2.5-alpha2-win32.zip twice now, and both times I’ve gotten the same error message while extracting, it’s

“! C:\Users\mami\Downloads\blender-2.5-alpha2-win32 (1).zip: The archive is either in unknown format or damaged”

Does anyone know how I can fix this?

Colourfulbanana.

Do you have 7zip? That would be the easiest way to see if it’s not a known format, which it should be, considering pretty much every OS has some archive extractor. After you try that, since you have 7zip now anyway, go to Graphicall.org and download a win32 build of 2.5.
