How to create a deployment project compatible with both XP and Vista?

[Juliano.net]

My application uses the ADODB.DLL on Windows XP, but when using
Windows Vista, this DLL doesn't exist because it's called MSADO.DLL.

How can I have multiple assembly versions on the same installer so it
chooses the right version (depending on the OS version)?

Now I'm using this code (just a detail: I generated an interop for
msado.dll, called interop.adodb.d ll)

peratingSystem os = System.Environm ent.OSVersion;

System.Reflecti on.Assembly ADODB_Assembly = null;

if ((os.Platform == PlatformID.Win3 2NT) && (os.Version.Maj or ==
6))
{
ADODB_Assembly =
System.Reflecti on.Assembly.Loa d("interop.adod b.dll");
}
else
{
ADODB_Assembly = System.Reflecti on.Assembly.Loa d("adodb.dll" );
}

Type type = ADODB_Assembly. GetType("ADODB. Connection");

Object conn = Convert.ChangeT ype(obj, type);

System.Reflecti on.PropertyInfo ProviderInfo =
type.GetPropert y("Provider") ;
System.Reflecti on.PropertyInfo ConnectionStrin gInfo =
type.GetPropert y("ConnectionSt ring");

But I receive an exception telling that it's searching for these DLLs
on C:\Windows\Syst em32 when it must be at the application directory.
