Hi guys! You can do it like this: [if you have the downloadable version] Use 7-Zip to extract the original installer (it's an NSIS one). Grab the .msi file (kis.en.msi) and create a WinRAR SFX switchless installer with the following comment: Setup=msiexec.exe /i kis.en.msi /quiet /norestart TempMode Silent=1 Overwrite=1 Title=Kaspersky Internet Security v188.8.131.524 To register it silently, export your key from within Kaspersky (it has got this option); or If you have an activation code, go to <https://activation.kaspersky.com/en/> and export it to a .key file. Put the .key file in the same folder where your .msi file is (it will get picked up and imported during install), then create your switchless installer. [if you have an OEM disc] The .msi is already on there.
