UDL Properties on 64-bit Windows

Since ArcGIS is still a 32-bit application, it requires that you install the 32-bit Oracle client. If you are trying to use a UDL file on 64-bit windows, and want to use the 32-bit Oracle Provider for OleDB, you need to open the UDL file with the 32-bit Ole DB Providers properties. Do that using the following command:

c:\windows\SysWOW64\rundll32.exe "c:\Program Files (x86)\Common Files\System\ole db\oledb32.dll",OpenDSLFile MyFile.udl

Using that command will give you the proper 32-bit Ole DB providers, and allow you to create/modify/test your UDL file.
