Advice Request Problem Installing Kaspersky Anti-Ransomware tool

[ForgottenSeer 77194]

After I run it, I got this pop up:

Program Compatibility Assistant
A driver cannot load on this device
Driver: kl1.sys

The setting that prevents it , is Memory Integrity.

Anyone having a similar problem or know how to fix it?

Your only option is to turn off memory integrity as Windows doesn't allow exclusions for it. You can do by going Settings > Update & Security > Windows Security > Device Security > Core isolation details, then switch memory integrity off.

I am aware of that but I am not willing to turn it off.

You have to choose between one of them. Kaspersky uses it's own hardware virtualization which makes it incompatible with the Windows built in one.

ok thanks for the info. The thing is when I install Kaspersky AV I don't have the same problem.
The anti-ransom tool installs and works with the exception of that driver.
Is it needed to function properly?

Exactly, Windows Code Integrity seems to use Microsoft HyperV, and can't be 2 HyperV running in the system at the same time, You have to decide Microsoft one of Kaspersky one

The Anti-ransom tool installs and the gui appears, but the driver did not install.
Does it mean the app will work properly without the driver, with only minor problems or
The app will seem to work but in reality it won't provide any protection?
I can still use it if it's the first case.

If the driver is not loaded, it's obviously the product will not work properly and/or will not provide the full protection as it was designed...
