Summary: Windows installer doesn't look environment variables

Initial Comment:
Windows installer doesn't look the environement variables to define where java is installed.

Since Java 1.5 the Windows registry isn't changed by the java installer so the easiest thing would ne to check the presence of JAVA_HOME or JRE_HOME environement variables to locate Java's installation dir.

I'm running Vista 32bits or XP 32bits.
Just after a fresh install of the os I installed Java5EE which contains
Java 6.

I haven't any javaw.exe in system directory nor JavaSoft key in windows
registry.

So the only thing the installer do is display a message that say that i
should install java.

Of course i solved the problem adding correct keys in windows registry but
i thought it would be better to correct the installer.
I already had that problem a number of time and seen the solution in the
jedit's forum : http://community.jedit.org/?q=node/view/1889

It happened to me a lot of time and i was bored to set the keys manually
so i wrote a C# project to do it for me (base on environement variables)
and wanted to make it accessible as a sourceforge project. But why would
everybody use an external tool if it's possible to change the installer
itself.

Why %SYSTEM_DIR%\javaw.exe should be present ? That's not normal location
for that file (on windows XP it was a Microsoft Java version i think).
And as the java installer doesn't set registry keys i don't see anything
else then environement variables.

First, are you running 64-bit Windows?

In a case the installer couldn't find javaw.exe in system directory,
it tries to get JavaHome from registry. This had been working for long
time before jEdit 4.3pre12, at least for me with JDK 1.5 with Windows XP
(32-bit). Are you sure that you don't have JavaHome in your registry?
If so, what happens if you actually try to launch jEdit?

I installed java 6 on windows XP and windows Vista and there is no
javaw.exe in system directory.

The patch only offers a last opportunity in case of all other tries
failed.

Why not give a last chance to those like me ?

The installer prefers javaw.exe in the system directory to one in the
directory where java is installed since jEdit 4.3pre12 so that user
don't have to reinstall jEdit after they upgraded the java installation.

Is there anything wrong to you?
