Windows x64 and x86 Registry

What is the difference between the registry in Windows x64 and Windows x86? I am registering a 32-bit component in Windows 7 x64. After registration, it is not possible to call it, and the registration is successful.

The fact is that you can't call a 32-bit component from 64-bit code. In Windows x64, there is a separate branch for 32-bit components. When registering a 32-bit component in the system, a prefix is added to its key, i.e. it turns out that it is registered under a different key.
