Executable in redhat6/fedora does not launch on doubleclick via desktop shortcut.

Ratzz

I have an application output created on Ubuntu . I have created installer for it using Qt installer framework.
After installing the installer in Ubuntu it creates desktop shortcut and it launches via double click . even the application directly launches from the installed path via double click.
When i install the same installer in red hat 6/ fedora it installs perfectly and desktop shortcut is created . But on double click the application doesn't open. while double clicking the application from the installed path opens the application.
The contents of .desktop file is shown below

Version=1.0
Type=Application
Terminal=false
Exec=Apppath
Name=untiteld

Even the shortcut created using Gnome application launcher does not launch the application via double click.
Its content are

#!/usr/bin/env xdg-open

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Icon[en_US]=gnome-panel-launcher
Exec=AppPath
Name[en_US]=untiteld
Name=untiteld
Icon=gnome-panel-launcher

But the maintenance tool shortcut which is in the same folder launches with double clik

Version=1.0
Type=Application
Terminal=false
Exec=Apppath_maintenanceTool
Name=untiteld

why the shortcut doesnot launch on double click??

Did you created launch shell file on the application installation folder?
If answer is NO:
Create a file with the name of executable file plus ".sh" with flowing content:

#!/bin/sh
appname=`basename $0 | sed s,\.sh$,,`

dirname=`dirname $0`
tmp="${dirname#?}"

if [ "${dirname%$tmp}" != "/" ]; then
dirname=$PWD/$dirname
fi
LD_LIBRARY_PATH=$dirname
export LD_LIBRARY_PATH
$dirname/$appname "$@"

Change your desktop shortcut to point to this file.

UPDATE: @Hamed-Masafi version seems better but make sure to export
the platforms folder too. (didn't see before i posted)

--
try to make it look for .SO files in the folder
Put in a loader.sh file (stupid forum) and let shortcut point to this.

FOLDER=`dirname $0`
LD_LIBRARY_PATH=$FOLDER
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$FOLDER/platforms
export LD_LIBRARY_PATH
exec $FOLDER/appname

@mrjj
exporting the path and running the exec works fine now :)
