Description

Sometimes due to different issues, the installation of Kaspersky Endpoint Security is corrupted. You can experience the Security Software is not running, Protection is stopped errors, and etc.

The normal troubleshooting process is as follows:

1. Use the Start/Stop application task to run KES.
2. Reboot the affected computer.
3. Install the latest KES Private Fix (hereinafter PF) and reboot the PC.
4. Reinstall and reboot KES.

Unfortunately, the steps above do not always help. In this case, you can use the KES Fix Package.

This script is designed to remove the previous installation of KES versions, clean the registry, perform several restarts, and finally install KES.

WARNING: KES will be installed in the default configuration, please work with SETUP.ini if you need to change components or installation settings. https://support.kaspersky.com/KESWin/12.1/en-US/127982.htm

Step-by-step guide

Prepare the files

1. Download the archive and extract its files into a separate folder.
2. Check if KES and PF from the archive are of the latest version.
3. There is a TXT file named Params.txt. Edit and set the correct username and password for KES removal (if password protection is required).
   You can add a few variations, one per each line. The first line in the Params.txt must be EMPTY for the purpose of removal without login/pass.
4. Add a license key to the package optionally inside the unpacked file.

(For more information, check README.TXT inside the archive).

Create a KSC package

1. Navigate to Advance → Remote installation → Installation packages.

Select Create installation package.

    2. In the New package wizard, specify fix_clean.cmd as executable and select the Copy entire folder to the installation package check box in the same window.

 

Create a task

1. Create a task for the desired machine.
2. Run the task (the task will complete with the error of an unexpected reboot).
3. The host should be rebooted once. After the reboot, a new version should be installed automatically.

Notes

1. The device will restart 3 times.
2. The package execution could take up to 10–15 min, depending on the OS config and reboot speed.
3. Do not disturb the target host until this operation completes (the host may reboot automatically up to 3 times).
4. Finally, KES + the latest patch should be installed.
