If you must use the old provider, you need to point Oracle. Data. Access. dll to the unmanaged Oracle Client Dlls that are of the correct version. If you have multiple Oracle Clients installed on your machine that maybe a simple as including the Dll. Path configuration variable see below in you app config, but you may also need to install a new oracle client to point to. Descargar Excel 2010 Gratis En Espanol Portable more. Full version First, lets make sure we understand the components of the old unmnaged provider not the new 1. Its made up of two pieces the managed. Oracle. Data. Access. Simply speaking, Oracle. Data. Access. dll is nearly just a wrapper, translating. ORACLE NET instructions for the unmanaged client. That said, when you load Oracle. Studio One 3 Pro V3.1.0 here. Data. Access there is a order in which it tries to locate the unmanaged client dlls that it needs. From the Oracle Documentation The Oracle. Data. Access. dll searches for dependent unmanaged DLLs such. Oracle Client based on the following order 1. Directory of the application or executable. Dll. Path setting specified by application config or web. Dll. Path setting specified by machine. Dll. Path setting specified by the Windows Registry. HKEYLOCALMACHINESoftwareOracleODP. NETversionDll. Path. Directories specified by the Windows PATH environment variable. So in your case, your app followed this process above and found a path that has unmananged dlls that are too old relative to the Oracle. Data. Access. dll assembly that you are using. It could just be that the only Oracle Client install on that machine is too old. But this comes into play if you have more than one client installed on the machine and the unmananaged files were found first in a different but older installation. If the later, the simple thing to do is use the dll. Path configuration variable in your config and point it at the correct Oracle Home Bin folder lt configuration. Dll. Path valuec oracleproduct1. BIN. lt oracle. If you want to install a fresh copy of the client, the xcopy version is the smallest and contains the instant client and point the Dll. Path above to this new location. But any oracle client install will work. But if you want to avoid all this unmanaged client resolution stuff, see if you can update your app to use the 1. Its also possible that you arent loading the Oracle. Data. Access. dll that you think you are if it is installed in both your bin directory and your GAC, but I think that is the less likely senario. See the assembly resolution process for more information.
