Upgrade from 11.1 to 11.1.2 "JRE libraries are missing or not compatible"

[tommeyers]

I am stuck with an error that I can't resolve; I have tried googling and even tried thinking: no luck

"JRE libraries are missing or not compatible"

here is what I do:
sudo su
cd /
mkdir tmp2
IATEMPDIR=/tmp2
export IATEMPDIR
export JAVA_HOME=/opt/ibm/cognos/analytics/jre/

Anyone have a suggestion?

Cognos installed directory is /opt/ibm/cognos/analytics/

cd /backup/cog_install/cog_11.1.2

Then run the install:
ca_instl_*.bin

then error

The install has not worked correctly. We you doing a silent install with a response file vs an install via the Java GUI?
