Low-Level Support Driver on Target Machines

The Runtime loads the low-level support driver if it is present when you start your executable. Several functions in the Utility Library, including CVILowLevelSupportDriverLoaded, require the low-level support driver.

Note Note  The low-level support driver is not supported on 64-bit systems.

On 32-bit OSes, the installation program installs the low-level support driver in the \Windows\system32\drivers directory. The installation program also adds a registry entry under the following key:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\cvintdrv

The following table shows the values the installation program sets for the Windows registry entry for the low-level support driver.

Type Name Value
DWORD ErrorControl 00000001
String Group "Extended Base"
DWORD Start 00000002
DWORD Type 00000001
