When attempting to deploy or install the Veeam CBT driver on a machine running Windows Server 2008 R2 SP1, the following error occurs:

When attempting to install the Veeam CBT Driver for a standalone Veeam Agent for Microsoft Windows deployment, this error will appear as:

Solution

As documented in the Veeam Agent for Microsoft Windows System Requirements, when installing Veeam Agent for Microsoft Windows on a machine running Microsoft Windows Server 2008 R2 SP1, the Veeam CBT driver is supported only if Microsoft Windows update KB3033929 is installed.

Verify that KB3033929 is installed by downloading and running the update. If the following message appears, proceed to the next section for information about bypassing the KB check.

KB3033929 is already install message
Note: KB3033929 was included in the October 2016 Security Monthly Quality Rollup  (KB3185330).
Before creating the registry value on this article, ensure that KB3033929 is installed on the system. If KB3033929 is not installed and the Veeam CBT driver is installed by bypassing the check for KB3033929, the OS will likely fail to boot.
