Assuming that you are installing PicoLog 5.24.8, please try the following:-
Progress bar only:
PicoLog_r5_24_8.exe /s /v"/passive"
No UI (also sets language to English, default device to USB TC-08 and installs drivers for all devices):
PicoLog_r5_24_8.exe /L1033 /s /v"DEFAULT_CONVERTER=81 INSTALL_ALL_CONVERTERS="Yes" /quiet"
Hope this helps,
