In large network you can use some software like https://www.exemsi.com/
to convert EXE to MSI file and install in by Software install task.
We test it and it is working find , just set to run certfix.exe after installation.
Update (Feb 10, 16:30 CET):
1, A fix tool that will replace ekrn.exe with a fixed version will be ready within today (Feb 10). The tool will need to be run on machines with affected ESET Security products that are malfunctioning. No restart should be needed to get the product work. The tool should work for affected Endpoint v5 as well as v6.5 products also on Windows XP and Windows Server 2003.
2, If you have an affected version of the product and it still works alright, do not restart the computer yet. Tomorrow (Feb 11) we'll be releasing Antivirus and antispyware module which will patch ekrn to fix the issue.
3, We should have 6.5 installers with a fixed ekrn.exe ready by tomorrow and will replace them in the repository too.
4, After remedying the issue, please consider upgrading to the latest Endpoint v7.2 wherever possible. While Endpoint v5 and 6.5 products will work until they reach EOL, we strongly encourage you to use the latest version which not only addresses bugs and issues from older versions but also brings substantially better protection against current threats.
@mcrouse in my case system date must be 7.2 or before, so it can 6.5 load correct and uninstall correctly. For installing another version system date must be today. If you are installing 6.6 or 7.x on 6.5, then the date must be 7.2 or earlier during installation, to be able to properly uninstall 6.5. You can then change the date to today before restart.
If adding the root certificate fails, we will attempt to add it the next time the system starts. Until then, there will be issues with SSL websites because of the missing root certificate and SSL filtering enabled.
