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

Incompatible operating system

Incompatible operating system (ESET security application)

You try to install an ESET security application that is not intended for your operating system (for example, you try to install ESET Endpoint Antivirus on a Windows Server).

Incompatible operating system (ESET Management Agent)

You have used an installer with a different bit number than your operating system. Check your operating system version and the version of the package. You can determine the version of the package from the package name. The string x86 or x64 is always present in the filename. For example, PROTECT_Installer_x64_en_US.

Invalid installer

The ESET PROTECT Live Installer becomes invalid if the referenced version of the ESET security application is no longer available for download. Generate a new installer.

The installation was not completed successfully

The installation was not completed successfully with the error code MSI 1303.

The Error Code: MSI.1303 indicates a conflict with your system permissions and the ESET security application installation. Try these solutions:

•Rerun the installer as administrator.

•Change the installation folder.

If you get the Error Code: WIN.1603, read the Knowledgebase article for more details on how to resolve the error.

The installation was not completed successfully with the error code WIN 1603.

You also may need to turn off the Real-time protection under Virus & threat protection.
