Symptoms
You are installing Agent on a Windows 2003 machine.
The installer shows the following warning:
The KB940349 update is not installed on this machine. Install this update to avoid disk backup failures
Cause
An outdated VSS version is installed on the machine. To guarantee correct backup functioning, we always recommend updating VSS components to the latest available versions.
Solution
As KB940349 is not available for download on the Microsoft website anymore, it isn't possible to install this specific update separately. Make sure that the latest updates for your operating system are installed. After that, continue with the installation.
In case of issues, contact Acronis Support.
