Installer log files are located here: C:\Users\%username%\AppData\Local\Temp\eset\ .

Below is a list of errors that can occur during the installation process:


Incompatible operating system


You try to install an ESET Security product that is not intended for your operating system (e.g. you try to install ESET Endpoint Antivirus on a Windows Server).


Installation has been interrupted (Error Code: WIN.1633)


You most likely have used an installer with a different bit number than your operating system. Check your OS version and the version of the package. The version of the package can be determined from the package name. The string x86 or x64 is always included in the name. For example: ESMC_Installer_x64_en_US.


The installation was not completed successfully


When the installation fails with this error message, you can use ESET Specialized Cleaner which automatically identifies and removes common malware infections. For more information, visit this ESET Knowledgebase article.


Out of disk space


This problem occurs when there is not enough disk space on the volume where you want to install ESET Management Agent. Make sure you have enough free disk space and then continue installation.


Invalid folder selected


The folder or path you have selected for product installation does not exist and cannot be created. Browse for a different folder.


This app can't run on your PC


To resolve this problem it is necessary to create a new installer in ESMC Web Console or in ECA Web Console.


Windows protected your PC


Windows prevented the installer from running due to security reasons. To run the installer, click More info to see the file details and then click Run anyway.


If you do not see the Run anyway button, or if the installer download/execution is blocked by Windows, you need to open the Windows Defender Security Center > App & browser control > Check apps and files and select Warn or Off. You also may need to turn off the Real-time protection under Virus & threat protection.



Application failed


Installation cannot continue due to damage of the installer package. The installer file can be damaged or the download did not finish successfully. Download the installer package from the ESMC Web Console or ECA Web Console again.


Windows cannot access the specified device, path, or file


This problem occurs when you do not have permissions to the file, the file has been deleted, moved or can be blocked by Windows. For more information, read the following Microsoft Support article.
