I downloaded server-jre-7u21-windows-x64.tar.gz from the link
Unzipped the .gz file and got file server-jre-7u21-windows-x64 without extension.
I tried to install it by just double click. But unable to install?
Can anybody suggest me how to do this?

This question came from our site for professional and enthusiast programmers.
OP probably already solved, but for others, I had the same problem- for some reason the file downloads as: server-jre-7u21-windows-x64.gz
When you extract it, you just get the tar file without an extension. Attempting to extract the tar (using 7-zip in my case) gives you invalid output (empty folders).
To fix, just rename the downloaded file to: server-jre-7u21-windows-x64.tar.gz
Extracting the gz then the tar should get you what you need.
AFAIK All you do is unpack it into a directory which you add to your path.
I would make sure you have a utility which can untar files.
