About a year ago, I installed Secunia on my desktop. I finally got around to putting it on my notebook. This was an issue I remember going through back then, only I don't remember how I resolved it.

Secunia shows:
C:\Program Files(x86)\Java\JRE1.6.0_02\bin\java.exe
Known issues with Sun Java JRE1.6/6x (Requires uninstall) Go to Add & Remove Programs
Update to a fixed version
JDK and JRE 6 Update 17
JDK and JRE 5.0 Updaate 22
Java SE for Business SDK and JRE 1.4.2_24
SDK and JRE 1.3.1_27 (for customers with Solaris)

Under Control Panel>Programs and Features, I only show:
Java 6 Update 2
Java 6 Update 17.
There is nothing else listed for Sun Microsystems.

Since I don't have Solaris, its safe to say I don't need the last download.
If it doesn't appear anywhere, would I need the Java SE for Business SDK and JRE 1.4.2_24?
Do I need to uninstall both Java 6 Update 2 and 17, and then reinstall the JDK and JRE 6 Update 17?
Do I also need to install the JDK and JRE 5.0 Update 22? It would appear to be an older version. Thanks for the help.

Hello Recruiter ,

JDK and JRE update 17 and 18 are both secure , you need one or the other . If you are not doing deveopment work you only need JRE .

Whether you have any programmes which require any other versions I cannot say . You can locate each folder using PSI and then rename it and see if that gives problems ; if not you can delete it .

I don't know if you know how to make use of PSI in "advanced" mode , so to be sure :-

here are some instructions to help you first of all get the best out of PSI :-

1)use PSI in "advanced" mode ;
2)in the "settings" tab make sure that the box in the first/upper section is NOT ticked in order to have the maximum info available ;
3)tell us in which "tab(s)" your problem programme is located ;
4)in that tab , click on the + in the box at the left end of the programme , the page will expand ;
5)in the expanded page , tell us what is written in the "installation path" ;
6)in the "toolbox" section , lower down , the link "technical details" should confirm the installation path details ;
7)click on the link "open folder" and you will see more details concerning the location of the "problem" .

Posting these details will help the Forum help you , if/when you have a problem .

An alternative is to ensure that you have the latest Java version :ie: u17 or u18 : and then load and run JavaRa which will uninstall all previous versions of Java for you :-

Ask if anything is not clear .


PS: this link tells you a bit more about the Java names and uses :-

Full link not working correctly :((, but you get the idea


It always seems impossible until its done.
