Problem with distibution of JET 3.5

I wrote an application with MS Visual C++ using DAO database access via Jet 3.5.

The application uses SQL functions SUM and AVG:

i.e.:
rs.Open(dbOpenDynaset,"Select Avg(einheiten) AS Emit,Sum(einheiten) AS Esum FROM gebuehr");

The programm runs well on this PC, where Visual C++ is installed.

When i distribute the application on customers PC by installing the programm and
jet engine from visual c++ cd (daosdk\redist) programm fails with access violation on
WIN95, WIN98 and NT4.0.
It fails on when using SQL function like AVG and SUM; all other Database Access functions
works well.

Somebody can help ?
