"Permission denied" error on .sh script on RHEL5

Question

root@server [/mnt/elm332/Setup/Linux]# ./setupLinux64.sh -c Unpacking JRE ... Starting Installer ... ./setupLinux64.sh: line 433: /tmp/setupLinux64.sh.28603.dir/jre/bin/java: Permission denied

root@server [/mnt/elm332/Setup/Linux]# whoami
root

Why would this be happening? Note that this is a mounted ISO file (copied in /tmp), and the permissions on that are:

 -rw-r--r--  1 root   root   554434560 Aug 26 16:05 elm3.3.2.iso

---

Line 433 is as follows:

"$app_java_home/bin/java" -Dinstall4j.jvmDir="$app_java_home" -Dexe4j.moduleName="$prg_dir/$progname" -Dexe4j.totalDataLength=73387877 -Dinstall4j.cwd="$old_pwd" -Djava.ext.dirs="$app_java_home/lib/ext" "-Dinstall4j.nolaf=true" "-Dsun.java2d.noddraw=true" "$vmov_1" "$vmov_2" "$vmov_3" "$vmov_4" "$vmov_5" $INSTALL4J_ADD_VM_PARAMS -classpath "$local_classpath" 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 10.0" 20 40 "Arial" "0,0,0" 8 500 -1 "$@"

Hi guys, thanks for your efforts to help. The issue was because of cPanel which was present on the server and preventing execution/creation of files in /tmp

From the help desk of the dedicated hosting provider:

"The installer has unpacked the install files in /tmp and is trying to run the install from there. cPanel is installed on that server, and one of the things it does is lock tmp so executables can't run from there (mount with noexec option). It's an additional security precaution to prevent someone from uploading a rootkit through an insecure website script."
