I tried the code below which worked fine on my friends machine but is giving an error on my machine.

'Add a reference to Microsoft Remote Data Objects 2.0
Private Sub Form_Load()
    Dim en As rdoEnvironment
    Set en = rdoEngine.rdoEnvironments(0) 'Error Line.
    MsgBox "Successful!"    'Not reached
End Sub

I tried the following things.
1. Checked the dependency information for msrdo20.dll.
    Everything was fine.
2. Replaced the DLL from my frnds machine and
   reregistered it.    Still not working.

Please help..

Which error? VB5 or VB6? If VB5, you need the enterprise edition.

Have a look at http://support.microsoft.com/default.aspx?scid=kb;en-us;Q177799

RDO is more than just a single DLL.  If you want to run a VB program that does database access then generally you have to install the Microsoft Data Access Components first.  This is usually distributed by the program's Installation program by including the MDAC_TYP.EXE  as part of the installation.  This is a Self-Extracting Installation program for the Microsoft Data Access Components.  I think that MDAC includes RDO as well as ADO and DAO components.....

if your machine already has MDAC on it, then you might need to see what version you have.  It's possible that your friend has upgraded to a more recent version of MDAC that includes all of RDO v 2.0, and perhaps your version has an earlier version of RDO.  Again, bringing over just one file wont be enough.

have you tried vb5cli.exe?

mdac won't help because it doesn't include RDO.
