Resolution:
BWC 5.5.1 is a simple service pack installer unlike BWC 5.5.0, which is a suite installer. In order to install BWC 5.5.1 in silent mode, we need to comment or remove ‘SW’ and ‘SP’ options from the response file. ‘SW’ and ‘SP’ options apply only to BWC suite installer and not for service pack installer.

While performing silent installation using the option:  -options &ltresponsefile>, the value for &ltresponsefile> must be absolute path and not a relative one. Also, using the response file, the installer can be run in GUI or Silent mode. Please find the steps for different modes below:

- GUI mode using response file (C:\temp\bwc_inst_resp) - TIB_bwc-simple_5.5.1_win_x86.exe -options C:\temp\bwc_inst_response
- GUI & Debug mode using response file (C:\temp\bwc_inst_resp) - TIB_bwc-simple_5.5.1_win_x86.exe -options C:\temp\bwc_inst_response -is:javaconsole -log #
NOTE: By running in GUI mode, you will be able to verify that the values from response file are properly prefilled in all the panels.

While doing installation in silent mode make sure to comment or remove the line "-silent" in the response file -

- Silent mode using response file (C:\temp\bwc_inst_resp) - TIB_bwc-simple_5.5.1_win_x86.exe -options C:\temp\bwc_inst_resp -is:silent -silent
- Silent & Debug mode using response file (C:\temp\bwc_inst_resp) - TIB_bwc-simple_5.5.1_win_x86.exe -options C:\temp\bwc_inst_resp -is:silent -log #

Attached is the support response file for reference.
