Hi. This works for me with avast pro 2014 (see here: https://www.avast.com/faq.php?article=AVKB18) avast_pro_antivirus_setup.exe /verysilent /noreboot /nosounds /instlang fr-FRThen, for license file integration: c:\Program Files\AVAST Software\Avast\aswChLic.exe "avast! license file.avastlic"But I still have to click once to activate the license file. If I could copy my "avast! license file.avastlic" to c:\ProgramData\AVAST Software\Avast\license.avastlicin my script then the all procedure would be automated. Corto
