Java Hell of versions #65392: Java does not load for non admin user on Windows 7

UPDATE: This does not work!!! The plugin is loaded, i.e. shown in about:plugins but does not start!!! When accessing a page it does not start java. So this remains unsolved and I can only use java when firefox started with admin privileges.


Firefox 7.0.1, Windows 7 x64 and java plugin not loaded. Only the development shows with about:plugin.

But it works with priviledged mode, i.e. user with elevated rights.

There could be a possible plugin scan issue and to remedy this you'll have to copy the plugin files ( npjp2.dll) to the firefox installation directory. And voila:

Java(TM) Platform SE 6 U20

File: npjp2.dll
Version: 6.0.200.2
Next Generation Java Plug-in 1.6.0_20 for Mozilla browsers



c:\program files (x86)\java\jre6\bin\new_plugin\npjp2.dll to C:\Program Files (x86)\Mozilla Firefox\plugins


I also tried copying it into the user plugin folder, same result.

TFTP over firewall (using tftpd32)

For the first time I have had the need to use tftp over a firewall.

I knew that port 69 was involved on the server side but what I did not know was that the data transfer is done over a new connection from client to server on a dynamic port!

But luckily with tftpd32 I was able to specify the local port pool and I have set it to 69:69. This worked like a charm.
