Veeam Backup & Replication C++ run-time components requirements

Backup and replication jobs processing Virtual Machines using Windows Server 2008 as a proxy server may report:
 

Working with VMware vSphere requires vddk of a proper version, which, in its turn requires Visual C++ run-time components. Veeam Backup and Replication does not perform its automatic installation on servers running Windows Server 2008, thus it should be installed manually.

Perform manual installation of the proper version of Visual C++ run-time components. Requires version may be checked in the following table:
 

VMware vSphere version	Visual C++ Redistributable Packages version
4.1. 5.0, 5.1	not required
5.5, 6.0	Microsoft Visual C++ 2008 Redistributable Package (x64)
6.5, 6.7	Visual C++ Redistributable Packages for Visual Studio 2013

  

While this article is specifically regarding Veeam Backup & Replication versions 9 and older. This error has been observed in Veeam Backup & Replication v10 and higher when security hardening using the registry value CWDIllegalInDllSearch is implemented.
