Veeam Agent: cannot update from 13.0.1.120 to 13.0.1.1009

[DatatoSecure]

Good day,

This is similar to this post veeam-agent-for-windows-f33/cannot-upda ... 00656.html

We can manually upgrade from 6.3.2.1302 to 13.0.1.120 or to 13.0.1.1009
But cannot update from 13.0.1.120 to 13.0.1.1009, it generates this error message:
Another version of this product is already installed.
Installation of this version cannot continue.

So on machines we tested with RTM & GA version: 13.0.1.120 (November 19, 2025), we have to uninstall the Agent before installing version 13.0.1.1009.
In one case a client is running PatchMyPC-HomeUpdater, so it has version 13.0.1.120.

Thank you.

Hi Francois

Yes. It‘s documented.
Please review KB4811.

Best,

Good day,

In order to unburden the forums, I think every error dialog box should have an error code. This way one could look it up and read the corresponding documentation.
