This method is called by a client to get a list of component full configurations for a component.

 HRESULT GetComponentVersions(
   [in] LPCWSTR pwszClsidOrProgId,
   [out] DWORD* pdwVersions,
   [out, size_is(, *pdwVersions)] GUID** ppPartitionIDs,
   [out, size_is(, *pdwVersions)] GUID** ppConglomerationIDs,
   [out, size_is(, *pdwVersions)] BOOL** ppIsPrivate,
   [out, size_is(, *pdwVersions)] LONG** ppBitness
 );

pwszClsidOrProgId: A string containing either the Curly Braced GUID String Syntax ([MS-DTYP] section 2.3.4.3) representation of a CLSID or the ProgID property of a component.

pdwVersions: A pointer to a variable that, upon successful completion, MUST be set to the number of component full configurations that exist for the component.

ppPartitionIDs: A pointer to a variable that, upon successful completion, MUST be set to an array of partition identifiers of the partitions in which the component full configurations reside.

ppConglomerationIDs: A pointer to a variable that, upon successful completion, MUST be set to an array of conglomeration identifiers of the conglomerations containing the component full configurations, in the same order as ppPartitionIDs.

ppIsPrivate: A pointer to a variable that, upon successful completion, MUST be set to an array of the values of the IsPrivate (see section 3.1.1.3.1) property of the component full configurations, in the same order as ppPartitionIDs.

ppBitness: A pointer to a variable that, upon successful completion, MUST be set to an array of the values of the ConfigurationBitness (see section 3.1.1.3.1) property of the component full configurations, in the same order as ppPartitionIDs.

Return Values: This method MUST return S_OK (0x00000000) on success, and a failure result, as specified in [MS-ERREF] section 2.1, on failure. All failure results MUST be treated identically.

Upon receiving a call to this method, the server MUST verify that catalog version negotiation has been performed by checking the negotiated catalog version (see section 3.1.1.5), and fail the call if not.

The server then MUST select the component as follows:

The server then MUST verify that the component has at least one component full configuration, and fail the call if not.

The server then MUST attempt to set the values referenced by the out parameters as follows:
