Member name	Value	Description
CLSCTX_NONE	0	No options.
CLSCTX_INPROC_SERVER	1	The code that creates and manages objects of this class is a DLL that runs in the same process as the caller of the function specifying the class context.
CLSCTX_INPROC_HANDLER	2	The code that manages objects of this class is an in-process handler. This is a DLL that runs in the client process and implements client-side structures of this class when instances of the class are accessed remotely.
CLSCTX_LOCAL_SERVER	4	The EXE code that creates and manages objects of this class runs on same machine but is loaded in a separate process space.
CLSCTX_INPROC_SERVER16	8	Obsolete.
CLSCTX_REMOTE_SERVER	16	A remote context. The LocalServer32 or LocalService code that creates and manages objects of this class is run on a different computer.
CLSCTX_INPROC_HANDLER16	32	Obsolete.
CLSCTX_RESERVED1	64	Reserved.
CLSCTX_RESERVED2	128	Reserved.
CLSCTX_RESERVED3	256	Reserved.
CLSCTX_RESERVED4	512	Reserved.
CLSCTX_NO_CODE_DOWNLOAD	1024	Disables the downloading of code from the directory service or the Internet. This flag cannot be set at the same time as CLSCTX_ENABLE_CODE_DOWNLOAD.
CLSCTX_RESERVED5	2048	Reserved.
CLSCTX_NO_CUSTOM_MARSHAL	4096	Specify if you want the activation to fail if it uses custom marshalling.
CLSCTX_ENABLE_CODE_DOWNLOAD	8192	Enables the downloading of code from the directory service or the Internet. This flag cannot be set at the same time as CLSCTX_NO_CODE_DOWNLOAD.
CLSCTX_NO_FAILURE_LOG	16384	The CLSCTX_NO_FAILURE_LOG can be used to override the logging of failures in CoCreateInstanceEx.
CLSCTX_DISABLE_AAA	32768	Disables activate-as-activator (AAA) activations for this activation only.
CLSCTX_ENABLE_AAA	65536	Enables activate-as-activator (AAA) activations for this activation only.
CLSCTX_FROM_DEFAULT_CONTEXT	131072	Begin this activation from the default context of the current apartment.
CLSCTX_ACTIVATE_X86_SERVER	262144	Activate or connect to a 32-bit version of the server; fail if one is not registered.
CLSCTX_ACTIVATE_32_BIT_SERVER	262144	Activate or connect to a 32-bit version of the server; fail if one is not registered.
CLSCTX_ACTIVATE_64_BIT_SERVER	524288	Activate or connect to a 64 bit version of the server; fail if one is not registered.
CLSCTX_ENABLE_CLOAKING	1048576	When this flag is specified, COM uses the impersonation token of the thread, if one is present, for the activation request made by the thread. When this flag is not specified or if the thread does not have an impersonation token, COM uses the process token of the thread's process for the activation request made by the thread.
CLSCTX_APPCONTAINER	4194304	Indicates activation is for an app container. This flag is reserved for internal use and is not intended to be used directly from your code.
CLSCTX_ACTIVATE_AAA_AS_IU	8388608	Specify this flag for Interactive User activation behavior for As-Activator servers.
CLSCTX_RESERVED6	16777216	Reserved.
CLSCTX_ACTIVATE_ARM32_SERVER	33554432	Activate or connect to a 64 bit ARM version of the server; fail if one is not registered.
CLSCTX_PS_DLL	-2147483648	Used for loading Proxy/Stub DLLs. This flag is reserved for internal use and is not intended to be used directly from your code.
CLSCTX_INPROC	3	A combination of CLSCTX_INPROC_SERVER and CLSCTX_INPROC_HANDLER.
CLSCTX_ALL	23	A combination of CLSCTX_INPROC_SERVER, CLSCTX_INPROC_HANDLER, CLSCTX_LOCAL_SERVER and CLSCTX_REMOTE_SERVER.
CLSCTX_SERVER	21	A combination of CLSCTX_INPROC_SERVER, CLSCTX_LOCAL_SERVER and CLSCTX_REMOTE_SERVER.
