Does Eset Endpoint products support Windows 8.1?


And what about Eset File Security and server 2012 R2?


Also, It seems that you are making a lot of improvements to the home user version woth both version 6 and 7, and I was wandering when theese will make it to the Endpoint solution?

The current versions of Endpoint Antivirus and Endpoint Security are NOT compatible with Windows 8.1.

Compatibility with Windows 8.1 will be available in later versions.


Please watch our ESET Support News for announcements about new releases.

Could you describe what part is not compatible please? I'm using ESET endpoint 5 on win 8.1 and it seems fine.....but what are the risks of me doing so? Am I protected? Am I risking system instability?

To say that it is not compatible suggests you know of a reason, would you mind posting details please?

Many thanks,

Hi Chadh


Thanks for you reply.


I need to say that I am not very impressed by this. Windows 8.1 is an update which is installed by the users directly from the Store without the need of the IT department. This also Means that we have a alot users running 8.1 now, without a supported antivirus solution.


So we need to uninstall Eset at theese computers and activate the free Windows Defender? if this is the case, i guess that many users will just stay with the free av.


You already have 8.1 support for home users, and it seems to me like you have making the home users a top priority. The endpoint version is already old, and could also benefit from all the new features you have provided in version 6 and 7 for home users.


It also took you about half a year to support Server 2012, which is waaayy too long, and now againg, no idea to when you will be able to support Server 2012R2.


I think, that you need to improve your support to business users.

Well it seems that you have just released an update with support for server 2012 R2, now we only need Endpoint to support Windows 8.1 :)

Support for Microsoft Windows 8.1 will soon be available for ESET's Endpoint programs.

I do not have a release date or notes that I can share at this point, but as soon as it's available we will let you know via the forum and other announcement mechanisms (Twitter, ESET's RSS feeds, etc.).

As of today, Windows 8.1 is supported by the latest version of Endpoint products, 5.0.2225. I have adjusted my previous post to reflect these updates.


If needed, you can download the latest version of your ESET product here:




Thank you very much for your patience.
