OMG i got the same problem! If you ever get it fixed please tell me?!Guys! Kaspersky is a joke!This company started down the slope. Now, I tried to install the version of 21.5, but can't started the application, because it have a problem with .NET Franwwork.I made harlan4096's suggestions, but dosen't work it. Try to reinstall the Kaspersky 21.5 and dosen't work. Soory Guys, but it is thus very little. I'm starting to think that Kaspersky is a set of problems. I'm not very anger. 21.3 is working on Windows 11, 21.5 dosen't.

And i reinstall .NET Framework, and i scan my healthy status of my operating system files. Everything is allright. It is now my and not your problem.
I use only Windows 11. And, i think, windows 11 is not very fresh operating system. Kaspersky hade time to do good job.I think it's a problem with your pc, you should format it. I just installed Kaspersky Standard on my windows 7 computer, it installed without any problems. Or maybe it's the operating system you have installed, if it's Windows 11 I recommend going back to 10. Greetings. The only detail is that the patch does not appear next to the version, only 21.5.11.384 and when I start all the programs, the option to uninstall does not appear, it is only in Add or remove programs, the rest, without problems, UNTIL NOW. I love the new Icon.
You are a lucky man! 21.3 working good, 21.5 is not. I wait for the Hungarian version, and i think it will receive by the patch "ZS".
On WMWare is working here fine! Because try it on a sharp system, not virtual machine!Anyway I just used the non California installer but selected English while installing, in a W11 fully updated (running inside VMWare), it has no apps, only just K. Plus, and seems working fine here:
