We realized, over a 64bit OS you may need to change the default application pool to accommodate 32bit applications. Please refer to this post

So, you are still using classic ASP or develop 32bit .NET applications using Visual Studio and Oracle databases on a Windows 7 64bit box and completely lost as connection cannot be established?

Here are few workaround solutions

Install the latest Oracle clients (both 64bit and 32bit)

If you installed Oracle client in the following folders (example)

D:\app\yourusername\product

right click on the folder, under security tab check whether authenticated users have read privileges.

If not, provide the basic privileges (Read & Execute, list folder contents, Read) Refer the image

Now add the user “IIS_ISURS” user and provide the same rights mentioned above

RESTART your Windows 7 “64bit” box now!

You can establish the connection from classic ASP like following

<%
    Dim adoCon                'Holds Connection
    Dim rsViewRecords        'Holds Recordset

    Set adoCon = Server.CreateObject("ADODB.Connection")
    if Err.Number <> 0 then 
        Response.Clear() 
        response.Write "<hr>ORASESSION Error<br>" & err.number & "  --  " & err.Description & "<hr>"
        response.End
    end if 

    adoCon.Open "provider=oraoledb.oracle;data source=test;user id=apps;password=apps;plsqlrset=true"

    Set rsViewRecords = Server.CreateObject("ADODB.Recordset")

    %>
