installer problem

[patrick]

I make an installer for my java application with install4j, bundling a
static JRE 1.5 . I run the installer on a machine with a JRE 1.6 already
installed.

I run the application and it runs OK up to this line:

Process proc = Runtime.getRuntime().exec(command);

where command is a keytool.exe command.
This gives an exception error:

Registry key 'Software\JavaSoft\JavaRuntimeEnvironment\CurrentVersion'
has value '1.6', but '1.5' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.


Any idea how to fix this?

Does the keytool.exe start a second JVM ??

Looks like it does and gets confused between 2 different installed versions
of the JRE.

Deleting a java.dll or uninstalling a JRE would not be nice option to fix
this.

There's nothing in your sample that shows what's actually contained in
the "command" variable, so I'm guessing it's basically just
"keytool.exe" or something close. If that's the case, then it seems
likely that the system's search path is being used to locate the
keytool.exe file, which you don't want. If you've bundled a JRE with
the application, you want to ensure that you use its keytool.exe by
specifying the path relative to your application's starting point.

No doesnt work. Ive tried it with the absolute path to keytool.exe and get
the same bug.
