Install SDK for Windows 7 64 bit

Posted on


I am trying to install Java SDK for windows 7 (Ultimate version, 64bit), I downloaded the following file from oracle website: jdk-7u9-windowsx64.exe. When I try to execute it, I get an error that it is not a valid win 32 application. I think the JDK version is correct. Can somebody help me out? Also, comment if you need more info about my machine configuration to help me out.

Edit: I have 4 GB RAM on my system , Dell Latitude E4310


It seems that you have 32bit operating system, so you cannot install 64bit application on it. Try check this by right-click on “my computer” and choosing “properties”.

I’d recommend you to try to install 32bit JDK.

This issue happens more often if the downloaded file is broken. It would seem like a complete executable file, and would run properly. But, believe me, it isn’t. The only remedy is to download the file once again and install.
