 Module Name:

    BaanERP5.cpp

 Abstract:

    Set 'lpstrInitialDir' in the OPENFILENAMEA structure passed to
    GetSaveFileNameA to be the directory the app is installed to.
    This information is read from the registry.
    
    No idea why this worked in Win9x.

 Notes:

    This is an app specific shim.
