An attempt to install the Backup Client fails with an error similar to the following one:

An error occurred during the installation of assembly
Please refer to Help and Support for more information.


This is an issue with your Windows operating system which is unable to install the redistributable components of C Runtime. For example, installation of Microsoft Visual C++ 2008 Redistributable Package (or similar) will fail in the same way.


To fix the issue, please run Windows System File Checker:

(!) You will need to have Windows Installation Disc to run the utility. It is strongly recommended to boot from the disc to run the system file check. See also Microsoft Knowledge Base Article 929833.

(!) If you do not have Windows Installation Disc at hand, you can always create it within Windows. Please see How to Create a System Repair Disk in Windows 7 and Vista.

  1. Hit Start-Run and type in cmd
  2. In the command line, issue the following command:

    sfc.exe /scannow

    (!) You can also view detailed instructions with screenshots at How to Run the System File Checker (Sfc.exe) Offline in Windows 7 and Vista.

This will check the system for corruption and repair the corrupted system files from the Windows Installation Disc.

More information

If the issue persists, please contact Microsoft Support since this is a Windows issue and may result in difficulties with installation of other applications as well.

You can also always contact Acronis Support for assistance.
