Hi, I have the same problem. In my company They were used cisco AMP a while. The version is 7.1.5. When we decided to go with Kaspersky endpoint security. The installation was blocked by Fatal error during installation. (Kaspersky Endpoint Security for Windows Setup cannot be performed because a third-party application is already installed on the computer: ClamAV 1.0.26 / gredAV. To install Kaspersky Endpoint Security for Windows on this computer, please remove the third-party application by using the standard Microsoft Windows tools or by other methods.) When I investigate this issue my findings are, 1 . The above stated issues have found the machines with windows 10 2040h or later edition. Which is not compatible with amp 7.1.5 edition. When the machines having cisco amp installed is upgraded to 2040h or later versions cisco amp no more listed in windows installed programs list. But the files were in program files, app data folder of users, programdata and also in registries. When we use revu uninstaller program. And manually search and removed all files. Even after we cannot install Kaspersky. The above stated message came again. I can't resolve the issue till now. Any body have solution for this?
