so /tmp/install is a binary file. Just do /tmp/install from /opt/BlueCat, you won't get the debugging information, but maybe now that you've reset /opt/BlueCat it'll work
so you've done steps 1 and 2 already? It looks like you're starting step 4 from / instead of /opt/BlueCat
Try this :
mv /opt/BlueCat /opt/BlueCat.broken_ferrari
mkdir /opt/BlueCat
cd /opt/BlueCat
bash -x /tmp/install
