Getting count of records in child table using select statement

I have a stored procedure in which i am trying to select all the columns of a table Table 1. There is another table which uses Table1 primary key as foreign key. I want to count number of records in this foreign key table with that select like this:

SELECT *, count(*) VacancyCount
    FROM Table1 hc
    LEFT JOIN Table2 hv
    on hc.CompanyID = hv.CompanyID  
    WHERE hc.Deleted = 0
    group by hc.CompanyID
    ORDER BY NameLang1

but it gives error:

Column 'dbo.Table1.NameLang1' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.

Please suggest how to fix this?
