In your SQL Server COM folder, there is a file named sqlvdi.dll. This is the backup library that SQL Backup uses. Try registering this dll manually e.g.
regsvr32 "C:\\Program Files\\Microsoft SQL Server\\80\\COM\\sqlvdi.dll"
This COM library might sometimes get unregistered when you install one instance of SQL Server, then install another instance, and later uninstall the later instance.
