Step 1: Download the Correct File From the official UZSoft portal, look for the "Offline Update" section. The file will look like: update_eav_v2.3.4_to_v2.5.0.uz.zip

Step 2: Place the File in the Right Directory Copy the .uz.zip file into the following folder (default path): C:\UZSoft\EAV\Updates\Offline\

Step 3: Launch the Offline Updater

Step 4: Validate the Update After the process (may take 5–20 minutes), verify:

At first glance, you might wonder: Why not just use ESET’s official offline update tool? The answer lies in accessibility, portability, and scale.

A: The archive itself is cross-platform, but the contained binaries are OS-specific. Download the correct UZ.zip for your OS (e.g., win64-uz.zip vs linux-x64-uz.zip).

You might ask: Why not just connect the EAV server to the internet for five minutes? In many UZSoft deployments, that’s impossible due to:

UZSoft recognized these needs and engineered the UZ.zip offline bundle specifically for IT departments that require physical media handoffs.


Because the UZ.zip is applied while the node is in standby, there is zero downtime. The caveat: your cluster must be on the same offline network segment.


  • Use ESET’s command-line update utility (ecmd or ecls) or the GUI to download latest update files:
  • Locate the downloaded update files. Typical paths:
  • Copy the entire Updater folder contents into C:\ESET_Offline_Update\updater\ preserving folder structure.
  • Optionally include lic.key or update credentials file if your deployment uses authentication.
  • Create a ZIP named eav_uzsoft_update.zip containing the updater folder root (so the archive extracts to "updater\…").
  • Transfer the ZIP to the offline target machine via USB.
