"Unable to execute the embedded application" error when you try to install the Microsoft Azure backup agent

Applies to: Azure BackupWindows Server 2008 R2 DatacenterWindows Server 2008 R2 Enterprise


When you try to install the Microsoft Azure backup agent on a server that's running Windows Server 2008 R2, the attempt fails. Additionally, you receive the following error message:

Unable to execute the embedded application to complete the installation.

Note This problem is known to occur with a virtual machine (VM) from a Windows Server 2008 R2 Datacenter SP1 image that was created from the image gallery. However, this same VM works as expected on Windows Server 2012.


This problem occurs because of an issue with Microsoft .VC90.CRT. To fix the problem, you must install the previous version of the Visual C++ runtime.

When this problem occurs, the following is logged in the Application log, and this indicates that Microsoft.VC90.CRT is the problem:

To resolve this problem, install the Microsoft Visual C++ 2008 Redistributable Package (x64).

Note Installing the latest version of the Visual C++ runtime does not fix this problem.
