Microsoft stops the support of root certificates that allow signing the code of the drivers that works on the operating system kernel level. Now drivers are signed with the WHQL (Windows Hardware Quality Lab) signature which is based on the SHA-2 (SHA-256) algorithm. Verification of such a signature requires SHA-2 support in the operating system.

Before installing a Kaspersky business solution on a protected device with an operating system from the list below, please make sure that the system has updates that bring SHA-2 support. If SHA-2 is not supported, installation will be interrupted. You can install the required updates for SHA-2 support and reinstall the application.
