This guide focuses on safely downloading and updating older versions of ESET Endpoint Security. This is often necessary when managing legacy systems or maintaining a specific software baseline within a corporate environment.
If you have an on-premises ESET PROTECT server, it includes a cached repository of all versions within your update channel. Access your server's Apache2\htdocs\ directory or use the "Software Install" task – you can select any version approved by your administrator.
ESET maintains a public repository of installers for major version releases. This is the safest method to get a clean, unmodified file.

Businesses often need to install previous versions of ESET Endpoint Security to match existing infrastructure. For example, older servers may not support the very latest ESET products. In these cases, administrators look for stable, older releases that still receive limited support or are compatible with their ESET Security Management Center (ESMC).
