    @mostafa-owiss Hello!
    you can use links like - https://www.kaspersky.com/downloads/plus
    or if you have your MyKaspersky account - you can download latest installers from it (there is download tab).

          This version doesn't handle reboots well. After restarting the PC, the program doesn't load. Manually opening it doesn't help either. You have to reinstall the program. After the next restart, it may or may not load.

          I encountered similar problem
          suddenly after a reboot the product won't load
          I surprisingly find that the K's %bases% folder in programdata is empty!
          Somehow this databases folder is totally wiped! only a single klids driver left.
          There may be an incident that trigger K itself to delete all files in bases. The klids.sys survived because it loaded to kernel.

                  Unfortunately, Kaspersky does not provide offline installation files for its final products and only needs to be installed online. This is a very big problem. Please put the offline installation files for the final products on the site. The second thing is that the ability to activate the 30-day trial period has been removed from Kaspersky products. Please fix this as well.

                    @Chengnan, hello!
                    This issue had been fixed. MR26 release build will run correctly.

                        So, what should those affected do before the release of MR26?

                          此版本让我重启应用以更新某些组件,执行重启应用的操作后会显示“某些保护组件已受损,建议您重新安装应用程序“
