The XCOM for Windows installer changed between XCOM r11.6 SP00 and XCOM r11.6 SP01 i.e. XCOM r11.6 SP00 used InstallShield while SP01 and later uses InstallAnywhere. InstallAnywhere creates an Uninstaller directory under the %XCOM_HOME% installation directory while the previous InstallShield does not. So the uninstall steps in the current online techdocs for XCOM for Windows reflect the latest InstallAnywhere behaviour.
