IC617 Running Issue at RHEL8.2

Hello,

First of all, I understand that RHEL 8.2 is not a supported version for IC617. But, as I already installed the Hotfix_IC06.17.722_lnx86.sdp (I haven't installed the base) and later figured out the compatibility issue, I like to see if it works before I reboot my system with other supported version of RHEL. I used Installscape for the installation and choose install from the local directory. But I got an error as it complains about the OS. I am adding snapshots of the errors I got. I would appreciate any suggestions.   

Here is a pic of my startup.ic6 file:

Thanks a lot for your time!
