Not able to create SSISDB catalog Getting the error below while trying to create a catalog in sql server 2014 integration services.
Any idea what I missed in installation or anywhere else?


  The catalog backup file 'C:\Program Files\Microsoft SQL
  Server\120\DTS\Binn\SSISDBBackup.bak' could not be accessed. Make sure
  the database file exist, and the SQL Server Service account is able to
  access it(Microsoft.SqlServer.IntegrationServices.Common.ObjectModel)
I had this problem and it wasn't related to user permissions.
I had done an earlier install of SQL server and chose to install many options except for 'Integration Services',
so I ran the SQL Server Installation Centre application again and this time chose to install the 'Integration Services' feature.
I think that the reason I could see the 'Integration Services Catalogs' node in SMSS despite not having installed 'Integration Services', was due to choosing to install 'Master Data Services' during my earlier SQL Server install.
