I am trying to install Rational License Key Server 8.1.3 on our RationalCLM Linux server using silent install mode.  RLKS is required for token licensing which we are adopting.

RLKS 81.3. requires IBMIM 1.5.2 or later; they come bundled together.  I tried to install in "non-administrator" mode; this would not work as RLKS would not install if IBMIM was not installed as admin.

I then tried to install as administrator and got the following:

ERROR: Installation Manager 1.4.3.1 (internal version: 1.4.3001.20110504_1325) is already installed at location "/opt/IBM/WebSphere/InstallationManager/eclipse" and is using "/var/ibm/InstallationManager" for its data location.  Use the installed Installation Manager.

I don't think the installed version of IM will work.  Can I update IM without any affects on the installed instance of WebSphere?  What if update is not possible and I must uninstall/reinstall IM?  This is on a PROD server so we cannot uninstall WebSphere, JTS or any other installed packages.

Linux server is RedHat 6.3
WAS is 8.0.0.4
Rational CLM tools are 4.0.1

Thanks,
Mike
