Hi, your SQL Developer has been installed as a component of your Oracle client. You can try and 'repair' your Oracle client installation from 'Programs and Features' if you like.

However, I prefer a separate install of SQL Developer, you can download the latest version here:

>> which one i have to select for repair
I suppose the JRockit ones although I don't see why there is no Oracle client in your list.

>>  i forget the passwords for some connections
You should remember then, store them in a password management tool. You can look up the password in each connection.

>> installing the latest version , how i can save the connections properties
Installing a new version offers to import the existing settings from the older version. The .ZIP file in the download you can just unzip in a folder and run it from there.

I would save your passwords (in case you forget them) and download the .ZIP file and run SQL Developer from the unzipped location.

I think you mean SQL Developer, right? Which one did you download?

This version: "Windows 64-bit - zip file includes the JDK 7" - has the correct JDK7 bundled, so you should not get a question about that. The other ones have installation instructions, did you follow them?

You can update your JDK7 here: http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html

You need the last one:
JDK7 update
But: since you are still using WindowsXP - you know that it is not supported? Better upgrade to Windows 7 or 8.

have you got message box asking Java.exe path, you should give correct path to new version Java.exe.
if you are not getting that box anymore. delete new SQL Developer folder and extract again from downloaded archive.
