We have an application which works perfectly on 32 bit windows. But the same running on 64 bit gets the attached errors. We have Oracle 10.2.04 64 bit Client installed on the Win 2008 64 bit server. The applicable bin directory has the Oracle.DataAccess.dll (2.112.1.2). Now the application is running as a 32 bit process. Would we have to install a 32 bit Oracle client instead, possibly? |

Look at the InnerException from the TypeLoadException: that should tell you what the problem is. But yes, my guess would be that a 32-bit process requires the 32-bit Oracle client: that's certainly an issue that we've seen. If the InnerException is BadImageFormatException then that is almost certainly the problem: again, the details of the exception should make it clearer. |

We did install the 32 bit Oracle client (10.2.03) on the Win 2008 Server. Still got the same exception, the inner exception states “Provider version not compatible with Oracle Client”. The Oracle.DataAccess.dll we include on the applicable folder has version 2.112.1.2. We deploy this exactly the same way on Windows Vista and it works fine (Oracle 10.2.03 Client + Oracle.DataAccess.dll 2.112.1.2) |
