Return value

If the function succeeds, it returns the major revision number in the high-order byte and the minor revision number in the low-order byte. Version 4.0 is returned as 0x0400. By default, version 4.0 is supported by Microsoft Windows 2000 and later versions of Windows. If an internal error occurs, the function returns 0x0000. Call GetLastError to obtain the error code for the failure.


This function returns version 4.0 of the configuration manager to ensure compatibility with version 4.0 and all later versions of the configuration manager, and to ensure compatibility with all applications that require version 4.0 of the configuration manager.

To determine if a specific version of the configuration manager is available on a machine, use CM_Is_Version_Available or CM_Is_Version_Available_Ex.

Functionality to access remote machines has been removed in Windows 8 and Windows Server 2012 and later operating systems thus you cannot access remote machines when running on these versions of Windows.
