The query cannot be executed because some files are either missing or not registered

В консоли EM вызываем

Open Table -> Return all rows

и получаем сообщение об ошибке:

SQL Server Enterprise Manager:

The query cannot be executed because some files are either missing or not registered.

Run setup again to make sure the required files are registered.

[ OK ] [ Help ]

Далее по клавише Help примерно то же самое:

SQL Server Books Online:

The query cannot be executed because some files are missing or not registered.

Query Designer cannot locate your query files and cannot run your query. You may need to reinstall the product.

Деинсталлировали SQL server, перезагрузили компьютер, инсталлировали заново SQL server...

Те же сообщения.

О каких файлах может идти речь?
