I need Java running on a number of computers and after I've reinstalled the newest version a number of times I still cannot open the Java control panel.  When I try opening the control panel it just opens the outline of the control panel and never finishes opening.  Any ideas would be great.

I recently installed Java 6_26 and it works fine for me.
What OS you are using?
Is Java installation otherwise working?
Does it happen on all machines?

I'm running the same version on both XP and Windows 7.  Installation appears fine and it's happening on all workstations.

Sounds like a mystery to me.
Do you have applets working in the browser ?

Read the link below, although it was some time ago and does not seem to be your issue,
and does not have obvious resolution
Still maybe check something about display setting thee and possibly other things

Strange story, but still read it (maybe you also have Cleartype):



FINALLY after much hair-pulling I found the solution to the problem (and an extemely unlikely solution at that)...

Downloaded the ClearType Powertoy from Microsoft and ran it. Disabled Cleartype. Problem solved!


Now the Java Control Panel opens normally, applets run normally. Re-enabling Cleartype breaks everything again.

This is happening on a Dell Precision 390, with three monitors - Two on an NVIDIA Quadro 550 and the third on an NVIDIA FX 5200. Latest drivers installed.

If anyone has any ideas why this is happening / or solutions, please...

Otherwise, I will ask for points to be refunded and question to be closed.

Thanks

I don't know what changed, but I can now get into the control panel.  The problem is now that when I verify my version of Java, I receive a very generic error:

Error.  Click for details.

I click on this and receive no further information.

You mean when you click About in the General tab ?

Or when you click View in Java tab?

From the Java website, there's an option to verify my version of Java.

Which is the website - I'll check what it writes for me.

There are two ways to detremine Java version locally.

You go to control panel - Java- General tab - About

and you open dos winodws and say

java -version

What does it say for you?

It's here: http://www.java.com/en/download/installed.jsp and click on the verify Java version.  I have the most recent one installed.  I've uninstalled/reinstalled a few times.

But it writes you valid version (the one you installed) in both control panel and using java -version command line?
It is only on that web page where it reports you an error?

Still don't understand - everywhere else - in control panel and on command line java -version -
you have good resopnses - it shows you something
like java 1.6_26 and only in the browser - when you go to that page you emntioned
that's where you are getting the error? Correct?

Taht is important to understand.
So that it seems that your installation of Java went well - it is somewhere
in configuration of Java for the browseer where you have a problem - that is the question.
Taht's why I'm asking about how it shows your java irresoective of your browser.

Yeah, just on that page and then on a website that requires Java I get the same error.  It states:

Error.  Click for details.

But I cannot click on that.

Within my browser java is enabled and I've removed about every possible restriction that could be causing the issue.  This is where I'm stuck, I don't understand why it's still giving me this problem.

So you see console?
And it looks normal, even though it reports Error on the page?
Do you have another browser?
Say, Firefox?

I see the console, I cannot use Firefox because the website I'm accessing doesn't support Firefox - it actually checks which browser is being used and anything other than IE it won't allow you login.

When you go to this Verfy java page in the console - it alsoo should write
the version of Java you are using. Waht do you see there - when it says
Error. Click for deetails on the actual page.

Also why can't you click on "Click for details"?

There was a configuration setting on my firewall that resolved my issue.
