I was unable to install the 3.0.1.1 Jazz Team Server and CLM
I was running the following in ksh on AIX:

(where $RTCLATEST=/rtc3011)

./userinstc -dataLocation $RTCLATEST/silent-install/data -silent -showVerboseProgress -nosplash -input silent-install-server.xml -acceptLicense


This failed repeatedly (even after I removed /rtc3011/silent-install)

Output was as follows:

On a whim, I decided to replace $RTCLATEST with /rtc3011, and the command was successful.

I have been writing instructions for the team, and trying to build a reusable script as I proceeded, thus the environment variables.
I could not find this Install Manager error anywhere, and thought I would post this to the forum in case someone else ever encounters it, I doubt I am the only one to try to write some user level scripts :)
