Cannot obtain Oracle Client information from registry.

The error you are facing says that Oracle Client is not installed or the bitness of the application doesn't match to the bitness of the client.

1.) Install Oracle Client

2.) Configure the connection to your server in the tnsnames.ora file.

3.) Make sure that the Platform target of your project matches the bitness of the Oracle Client. For example, if you had only installed Oracle for Windows (x64) 64-bit, the Platform target should be "x64" (not "Any CPU").
