I have a big problem. I have design 3 datareports based on dataenvironement. All of them work on the developpement machine but when i install my progam on a empty computer (running only WinNT 4 Sp6), the program return error number 730 (error defined by the application or the object). I use in a form:

DATA_Report.Connect.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & app.path & "TEST.MDB ;Mode=Read;Persist Security Info=False"

to set the connection to the right database, then i try to open the datareport. On my developpement machine, everithing works well but on the developpement machine, it return the error 730.

I'm using Visual Studio Installer for distributing the application. I assume this installer incorpore all the files needed.

If anyone have an idea, it will be welcom cause i'm completly lost!

thanks a lot.
