Why does the Muse setup kit does not perform an upgrade?

InstallShield defines the Muse environment variables (MUSE_HOME, USE_HOME, ICE_HOME, MODULES_HOME) in the system wide profile file for Bourne shell and Bourne compatible shells : /etc/profile. The section from the /etc/profile added by InstallShield on a normal Muse installation looks like the following:

    # Begin INSTALLSHIELD Environment Variable Section
    # Do not edit this section manually.
    # var 0 MUSE_HOME=/opt/muse
    MUSE_HOME=/opt/muse
    export MUSE_HOME

    # var 0 ICE_HOME=/opt/muse/use/ice
    ICE_HOME=/opt/muse/use/ice
    export ICE_HOME

    # var 0 MODULES_HOME=/opt/muse/use/modules
    MODULES_HOME=/opt/muse/use/modules
    export MODULES_HOME

    # var 0 USE_HOME=/opt/muse/use
    USE_HOME=/opt/muse/use
    export USE_HOME

    # End INSTALLSHIELD Environment Variable Section
    
In the setup upgrade process, InstallShield edits the /etc/profile file and makes changes by identifying its section inside the file. If this section is modified, then InstallShield will stop from running, thus the whole upgrade process will fail.
