Hi guys, Doing test see the patch can’t be installed if in HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products\F80ECE4F9E052E442A3FF2C3D8FDE861\SourceList the PackageName key is not correctly configured. In several PC I found the key PackageNameNotExist It affects if like uninstall the KES too. Now, fix this issue, I tried the patch in three devices and in two worked fine but other don’t. i like try add the patch to installation package but the procedure available in https://support.kaspersky.com/14409 isn’t clear for me, particularly to build the new package. This a big problem to our customer. I hope a quickly fix and a compensation to customer subscription. Best Regards Luis Arturo
