I am running 64 bit. I tried the cmd java - version and it says: Java version "1.8.0_31" Java(TM) SE Runtime Environment (build 1.8.0_31-b13) Java HotSpot(TM) 64-bit Server VM (build 25.31-b07, mixed mode) Brian From: Hans Forbrich [mailto:fuzzy.graybeard@xxxxxxxxx] Sent: Monday, February 02, 2015 3:08 PM To: Zelli, Brian; oracle-l@xxxxxxxxxxxxx Subject: Re: sql dev The question is whether you are running Windows 7 32-bit or Windows 7 64-bit. That can be determined by going to the Control Panel and opening the System applet. I have had no problem using the 4.1 on a Windows 7 64-bit environment using the complete download, which includes the JDK. I am currently trying to reproduce your challenge on a Windows 7 32-bit environment, using the 32-bit JDK and the same SQLDeveloper you downloaded. Please open a command box and run "java -version" and post the output. /Hans On 02/02/2015 1:03 PM, Zelli, Brian wrote: Yes, I am on the sql developer 4.1 early Adopter page and the download says Windows 32/64bit. That's what I downloaded.
