This issue is for the following error message:
Could not load file or assembly 'Oracle.DataAccess, Version=188.8.131.52 or a variation of it (sometimes the version is different).
This occurs in:
1) Data Manager or other Client/Server or command line EXE versions
Details: Unable to launch Data Manager on a Windows 10 machine with Oracle Client 12.2.0 (32-bit) or higher (32-bit version still required even if it's a higher Oracle Client version.
Data Manager appears to be configured correctly with the correct setup. However when we launch the application, we get a message that indicates that the Oracle.DataAccess could not be loaded. The system cannot find the file specified. The installation was done exactly the same as a previous version with the 184.108.40.206 software but with earlier Operating System and Oracle client versions.
2) EIP software when launching the initial page, get the same message.
