InprocHandler
Specifies whether an application uses a custom handler.
Registry Entry
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID
{CLSID}
InprocHandler = handler.dll
Remarks
This is a REG_SZ value that specifies the custom handler used by the application. If a custom handler is not used, the entry should be set to Ole32.dll.
If a container is searching the registry for a custom handler, the 16-bit version has priority with a 16-bit container and the 32-bit version has priority with a 32-bit container.
