VBA - Controlling Access from Word: Create .mdb & table without opening Access?

Hi All

Please can you tell me if, using VBA from Word, it is possible to create a new table in an existing Access database without opening Access?  Currently I am using the attached code which, although it works fine, displays a macro security warning when it opens the database.  I know that I can set the macro security in Access to low, or digitally sign the code, but am thinking that, if I can achieve this without actually opening Access, then I won't need to do either.  Also, would Access need to be installed on a user's machine in order for this code to work?  If so, is there a better way to do this so that it doesn't need to be installed?

Any help appreciated as always.

Set objAccess = CreateObject("Access.Application")
With objAccess
    .OpenCurrentDatabase (C:\Test\MyDB.mdb)
    Set dBase = objAccess.CurrentDb
    Set tdf = dbs.CreateTableDef("Contacts")
    Set fld = tdf. _
    CreateField("Surname", DB_Text, 50)
    tdf.Fields.Append fld
    dBase.TableDefs.Append tdf
End with
