Installing Rational License Key Server on Scientific Linux 6.9

Hello,
Just a background on our environment:
- Currently running Scientific Linux 6.9
- Installing IBM Rational License Server version 8.1.4 (version we currently have available on our old server)
- Following these instructions for installation: https://www.ibm.com/support/knowledgecenter/SSSTWP_8.1.4/com.ibm.rational.license.doc/topics/t_install_lic_unix.html
- Currently are running ibm doors and the rational license key server on the same host
I followed the prerequisites (following this page http://www-01.ibm.com/support/knowledgecenter/SSSTWP_8.1.4/com.ibm.rational.license.doc/topics/t_install_lic_unix.html) and I am currently trying to install the application from the terminal and I am getting this error:
[root@eng-ibm-doors disk1]# ./launchpad.sh
./launchpad.sh: line 64: /root/RationalInstallation/RationalLicenseServer/RLKSSERVER_SETUP_LINUX_X86/disk1/launchpad/SetArchitecture.sh:Permission denied

env: /root/RationalInstallation/RationalLicenseServer/RLKSSERVER_SETUP_LINUX_X86/disk1/launchpad/Firefox.sh:Permission denied
I get this same behaviour whether I add sudo in front of the command or not. I tried running this as our doors user but the script just completes without prompting anything to me or installing anything.
Is there any reason as to why this would be happening?
Thanks

Do you happen to know the switches I have to use for installing with console mode? I might be missing it but I can't seem to find it in the documentation. I did find a console install file in RationalLicenseServer/RLKSSERVER_SETUP_LINUX_X86/disk1/InstallerImage_linux_gtk_x86 but I get the same permission denied error even as root user
