Failed to initialize Microsoft .Net Framework

[alepcxd]

Hi everyone.

I recently updated to Kaspersky Premium (from Cloud Security Free), when the program updated and it was about to open, the following error appeared

"Failed to initialize Microsoft .Net Framework. Please Reinstall it"

I tried to reinstall Kaspersky, I installed and Reinstalled .Net Framework 4.8 and 4.8.1, I installed Desktop Runtime 5.*.* and 6.*.*, I used the fix dotnet tool and I have .Net 7.0.

I really do not know what to do.

- OS is Windows 11 Pro 22H2

- The Kaspersky product is Kaspersky Premium (installed today, 2/27/2023)

Experiencing the same issue here, tried almost everything, only Kaspersky having this .NET issue.

Same problem here running Windows11 on  a near-new computer. I have tried updating Windows, running the "fix" tool and fiddling with the apps on the control panel to no effect.

 

it looks as if something in a recent windows update may have upset Kaspersky as everything else works o.k..

I faced the same error. And the first solution in the link I gave below worked.

Failed to initialize Microsoft .NET Framework Error (Solved)

You can encounter a.NET Framework or.Net Desktop Runtime error during the installation or start of a Kaspersky application. Solution If the.Net Framework error occurs: Download and run Microsoft.NET Framework Repair Tool. Follow the steps of the installation wizard and then restart the computer.
