Another update: While Java is still working for me, other people have resolved their problem below. Read the comments for a solution.
Update: I still get hits to this post. Java works on my Vista 64 installation for both Internet Explorer 7 and Firefox 3.

I can’t get Java to run from a web browser in Vista 64 bit version.
I had to take an unplanned day off Friday. The day before I had gotten my remote access key fob so I figured I’d try using the browser based remote access into work.
I was in for a surprise. Like many solutions, work’s remote access relies on Java running in a browser. I had not yet needed Java in the months that I installed Vista 64 bit so I had to install it.
On Firefox (a 32 bit app) it kept dying when I tried to install it. On Internet Explorer 7 (also a 32 bit app) it looked like it was working but the browser would hang when I tried to reload it. Once I thought I had it installed but Internet Explorer 7 kept hanging and Firefox would just close whenever I hit a page with Java in it.
Looking this up using Google was kind of helpful but it just confirmed that I could probably get the 64 bit version running independently for stand alone apps like Azureus but being able to run it in a browser was not going to happen.
I’m going to re-install the 64 bit Java run time and try the web site in 64 bit Internet Explorer 7 (yes, they have a seperate executable and shortcut for the 64 bit browser) but I don’t think this will work due to changes in Internet Explorer.
This morning I used Synaptic and installed the sun-java packages for version 5. Remote access worked fine in Ubuntu. How ironic is that when Citrix Metaframe runs on Ubuntu but not on a Microsoft operating system?
I try to install the Java (version6, update 11) plug-in for firefox3 but it just won’t work. It is in the list of plugins, but java-applications on websites are just a blank square. (I am using Vista 64bit)
It works in IE 32bit (but not in IE64bit)
Are there any solutions yet? I am not the only person with this problem I assume.
Dimitri,
Unfortunately all I can recommend is that you completely remove Java from your system and try installing a new copy.
Java keeps multiple versions of itself and that might be causing a conflict.
Good luck.
It’s a new computer, there wasn’t any java on it. I installed en re-installed the JRE6(update11) a few times, but it still won’t work in Firefox. It shows himself in the plugin/addon list. But java applications won’t work.
Had the same problem, and found a way to fix it!
Disable all the java extensions in your firefox, and then shut it down. Next: I just copied all the dlls from the Java folder in program files into mozilla firefox\Plugins directory. Start firefox again and then it works perfectly.
Andre, thanks for that. I really did not have anything to offer as Java now works well for me.
Hello!
The only 3 DLL’s you have to copy are:
NPOJI610.dll
NPJPI160_11.dll
npdeploytk.dll
This used to be a problem in the Java 1.4/Firefox 1.x days. It was fixed in the past, but it looks like it’s back.

Same problem here, could not get java 32 bit working in Firefox 32 bit on Vista 64 bit.
The copying of those 3 dlls to the FireFox plugin folder worked a treat.
Thanks a lot! I had the exact same problem with Vista x64 + Firefox 3.0.5 and Java6 update 11. After copying the dll files everything works again.
Wish I could take credit, but Andre and Timothy posted the solution
Glad it’s working for you now.
So far there are no flash or java plugins for 64-bit internet explorer. Java should be ready soon (an update to version 6) but can’t say exactly when.
Java is working in 64 bit Internet Explorer. New update: Version6 Update 12!
Had the problem with FireFox 3.0.7 , Java 6.0_12-b04: Java Applets were blank.
Vista x64, Java Plugin in Internet Explorer worked just fine.
Couldn’t find a solution on the net. Futzed for a while and found that you need to do the following:
1) go to the Java Control Panel (search to find out how)
2) Advanced | Java Plug-in
3) _Disable_ “Enable the next-generation Java Plug-in (requires browser restart)”
4) Make sure to enable Mozilla family in Default Java for browsers
Hope this helps someone!
Jeff,
Thanks for the instructions. This page gets a lot of hits, so I am sure you’ve helped out somebody
Yes copying the 3 dll’s seems to have enabled Java. I’m just wondering when an update comes will I have to recopy these 3 dll’s?
You do have to copy the dll’s again when Java updates.
thanks a lot Timothy J. Massey it worked just great been at it all day and also reintalled vista twice actually it only needed the two plugins NPOJI610.dll
NPJPI160_13.dll
_13 dll is because I am on latest java with 3.10 firefox
For some re the plugins dont install
A BIG THANK YOU TO ALL AND THIS SITE googled it
by the way had the same problem in ie8 but all i had to do was disable and enable the add ons

Thank gawd for you guys…this had been annoying me for days! wish there was some way to get this to the top of the search list on google!
