The InprocServer entry is relatively rare for insertable classes.
In-process servers are currently registered using the InprocServer registry entry. The 32-bit and 64-bit in-process servers should use the InprocServer32 entry. If a container is searching the registry for an in-process server, the 16-bit version has priority with a 16-bit container and 32-bit version has priority with a 32-bit container.
