What if the installed Siemens version is no longer supported by the new BCT software version?
During the installation of a BCT software update, the installer will check if the currently installed Siemens software version is compatible with the new BCT software version. If it is not supported, a message box will appear in the installer, indicating this and prompting you to choose one of the supported Siemens software versions.
Once you chose a compatible Siemens software version, a notification will appear, informing you that the files supporting the previous Siemens software version will be deleted from the BCT installation.
Manual changes made to the environment variables since the initial installation, will affect the Siemens software version in the BCT start scripts.
If no manual changes have been made to the environment variables, the BCT installer will automatically update the relevant environment variables. However, if manual changes have been made, the environment variables need to be adapted to the new Siemens software version after installation.
