Your system has note been modified. To complete installation at another time, please run setup again. Click Finish to exit the wizard."

Bootstrapped InstallShield InstallDriver install was found to be creating second instance in DCOM as "InstallShield InstallDriver (2)" and in this application the identity is set to run as "The interactive user" and it should be set to "The launching user". However changing this in DCOMCNFG.EXE does not help because the setup.exe just reconfigures DCOM back to run as "The interactive user" which again breaks the installation.
