On May 10th Microsoft released KB5013943, once installed on Windows 11, it may disable .Net 3.5 and the user will not be able to start the Kaspersky product or have trouble installing/uninstalling the product.

Workarounds:

1) Activate .Net using instruction:

Activate .NET Framework 3.5 on Windows 11, 10, 8.1, 8 - .NET Framework | Microsoft Docs

2) Or run in CMD (run CMD as administrator):

dism /online /enable-feature /featurename:netfx3 /all
dism /online /enable-feature /featurename:WCF-HTTP-Activation
dism /online /enable-feature /featurename:WCF-NonHTTP-Activation
