eclipse 3.6.2 download cant open folder

I am trying to download the Eclipse classic into my开发者_开发技巧 windows machine.(Version 3.6.2 for Win 32 bit). When i try to open the unzipped folder, it gives out an error "cannot open folder". I think it is the problem with unzipping. I tried to download it thrice but still get the same error. Can someone help me out with this issue?I am downloading this as the first step of installing Android SDK.

Check the downloaded file size against the file size specified on the download site

Is it the same? If it's different your download may be corrupt.

If it is the same - did you try to unzip, or just open it?
