Here you can see two COM+ errors, one of them refers to SnapVssProvider and the second to snapapivss.dll. This means that the issue is with Acronis VSS Provider installation.

Here are two error codes that appear in the log:

  • 0x80110401 - Errors occurred accessing one or more objects - the ErrorInfo collection may have more detail
  • 0x8011041A - DllRegisterServer failed on component install

Most probably, the Volume Shadow Copy service is disabled or not started. You should make sure it is enabled and then start it. If it fails to start due to any reason, this means that there are some problems with VSS subsystem itself.

If starting Volume Shadow Copy service does not help, please proceed as follows:

  • Delete Acronis VSS Provider from Control Panel -> Administrative Tools -> Component Services -> Computers -> My Computer -> COM+ Applications -> System Application
  • Delete the \Windows\System32\snapapivss.dll file if it exists
  • Find and delete all registry keys (Start -> Run -> Regedit -> CTRL-F) which contain the following GUIDs:
    • F5DBCC43-B847-494e-8083-F030501DA611
    • 89CDAF20-82B6-42cd-A4B4-573C81999C35
    • 5FC845EB-F299-40f0-9725-34045F7EA8BA

      There will be keys with names beginning with SnapVSSProvider when you start searching for 5FC845EB-F299-40f0-9725-34045F7EA8BA. These keys should also be deleted.

  • Reinstall the product.
  • Reboot
