Introduction If you have arrived at this article searching for "oracle.dataaccess.dll version 4.112.3.0 download" , you are likely a .NET developer or a database administrator maintaining a legacy application that connects to an Oracle Database. You may have encountered a FileNotFoundException , a BadImageFormatException , or a version mismatch error stating: "Could not load file or assembly 'Oracle.DataAccess.dll, Version 4.112.3.0' or one of its dependencies." This specific version— 4.112.3.0 —corresponds to Oracle Data Access Components (ODAC) 11.2 Release 4 (11.2.0.3.0) . It is not the newest version (as of 2025, Oracle’s current managed driver is much later), but it remains critical for applications built on older frameworks such as .NET Framework 3.5, 4.0, or 4.5.
If you are building a new application today, avoid using this version. Instead, use the latest from NuGet. However, if you are maintaining an existing system—or deploying a legacy ERP—this guide gives you everything you need to successfully acquire, install, and resolve errors related to Oracle.DataAccess.dll 4.112.3.0 .
| Solution | Effort | Benefit | |----------|--------|---------| | | Moderate | Same 4.x assembly version but updated patches. Use binding redirects. | | Switch to Oracle.ManagedDataAccess | Medium | No Oracle Client required, cross-platform, easier deployment. | | Containerize the legacy app | Low | Use a Windows Docker container with ODAC 11.2 pre-installed. |
