These are the instructions I found on line to install in silent mode. The instructions can be found here:
https://help.kaspersky.com/KART/3.1/en-US/146392.htm
The first instruction states this:
Open the email you received to download Kaspersky Anti-Ransomware Tool for Business and click the Terms and conditions link.
The End User License Agreement, the Privacy Policy, and the Supplemental Statement will be downloaded to your computer.
There is no Terms and Conditions link in the email that i received. However I can download the tool. But still, I cannot install the product in complete silent mode.
