dotConnect for Oracle on x64 Windows with x86 Oracle Client

Hello!

I am using OCI.
dotConnect for Oracle on x64 Windows with x86 Oracle Client says:

System.InvalidOperationException: Cannot obtain Oracle Client information from registry. Make sure that Oracle Client Software is installed, or use the Direct mode when connecting to server.

x64 Oracle-Client works. Can't i use x86 Oracle Client?

Can't i use x86 Oracle Client?

Yes, you can. The bitness (x86 or x64) of your application and the bitness of your Oracle Client must be the same.

If your application is x86, Oracle Client must also be x86. If your application is executed as an x64 application, Oracle Client also must be x64. Thus, in order to use an x86 Oracle Client, you should set Platform target property value to x86 in your project properties.

So "Any CPU"-Configuration will not work?

[Pinturiccio]

Application with the "Any CPU" configuration can be run both as x86 or as x64 on an x64 computer in different cases. If you know the bitness of Oracle Client on the target computer, it's better to specify the bitness of your application explicitly in order to have the same bitness of the application and of Oracle Client.
