I've also had trouble installing and running loadUI version 1.5 in Fedora13 (x64). The problem is the loadUI installation program comes with a 32 bit version of the JRE which fails to run on the x64 OS.
$ bash loadUI-1_5_0.sh
Unpacking JRE ...
Preparing JRE ...
loadUI-1_5_0.sh: bin/unpack200: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory
Error unpacking jar files. The architecture or bitness (32/64)
of the bundled JVM might not match your machine.
The linked to forum post provides some help with getting the installed version to run, but the install script problem requires some finagling. These instructions assume you have a copy of Java 6 installed and correctly configured for your Fedora.
Step 1: copy the install script to a known location
$ cp loadUI-1_5_0.sh /tmp
$ cd /tmp
Step 2: get a copy of the expanded install script
$ export INSTALL4J_KEEP_TEMP=yes
$ export INSTALL4J_TEMP=/tmp
$ bash loadUI-1_5_0.sh
Step 3: Run the installer
$ cd /tmp/loadUI-1_5_0.sh.XXXX.tmp/
$ java -client -Dinstall4j.jvmDir="/usr/java/latest" -Dexe4j.moduleName="/tmp/loadUI-1_5_0.sh" -Dexe4j.totalDataLength=98859035 -Dinstall4j.cwd="/tmp" -Djava.ext.dirs="/usr/java/latest/lib/ext" "-Dsun.java2d.noddraw=true" "-Di4j.vmov=true" -classpath "i4jruntime.jar:user.jar" com.install4j.runtime.Launcher launch com.install4j.runtime.installer.Installer false false "" "" false true false "" true true 0 0 "" 20 20 "Arial" "0,0,0" 8 500 "version 1.5.0" 20 40 "Arial" "0,0,0" 8 500 -1
Once the graphical installer is complete, create a custom script for launching loadUI and placed it in /usr/local/bin:
#!/bin/sh
cd ~/eviware/loadUI-1.0.2-SNAPSHOT
javaws loadUI.jnlp
