[izpack-users] Installer for VISTA - works fine with a Launcher!

[Markus Schlegel]

Hi all

I have tested my Installer on Vista (English UI, German LanguageSettings) now. My installer includes all the patches I have published on the list recently, especially the "Program Files" Folder Patch.
It works, since I use a Launcher (tested with Launch4J which is an exe file that wraps the jar-file, and a Launcher generated with NSIS (35KB exe file that uses the jar file)).

Both launcher will correctly ask for elevation - or the admin credentials if logged in as a User only. The elevated access token is then sent along with the fork to all processes started from the launcher and also from the installer.

When I try to execute the jar file, it fails (explorer hangs). This is what has been reported by Roland...

It seems, that the Solution is to use a launcher. Which one depends on your preferences. The Pro of using a launcher is (especially applies to Launch4J), that it searches for an appropriate Java VM for your Installer (either one that is delivered along with your installer or one that is installed somewhere on the system) and displays the Java Download Page if it couldn't find a JRE.

So I think this is rather an improvement to the current "jar only" solution.

Regards
Markus

This should not be. We have had a verification of writeable.
May be I must show...

May be, but I am not confident. We have a program change (fork?) from the launcher to java.exe with the installation. I assume that MS do not give the special process token to the child process.

I will look if I have a system and test all possiblities (if I have time). But this will be not before January (hollidays...).

Cheers
