Microsoft DirectX 8.1 (C++)

DSETUP_CB_UPGRADEINFO

Passed as a parameter to the application-defined DirectXSetupCallbackFunction. It contains valid information only when the Reason parameter is DSETUP_CB_MSG_CHECK_DRIVER_UPGRADE. Callback functions can use it to get status information on the upgrade that is about to be done.

typedef struct _DSETUP_CB_UPGRADEINFO {
    DWORD UpgradeFlags;
} DSETUP_CB_UPGRADEINFO;

DSETUP_CB_UPGRADE_KEEP
The system might fail if this device driver is upgraded. Upgrade not allowed.
