serial number daqmx 8.3.1 VISTA

[pejo1964]

I developed a software based on CVI8.5 that uses the DAQCard-6036E device. It works perfectly in Windows XP with Tradition NI-DAQ and DAQmx.
Now I need to migrate to Windows VISTA. Since DAQmx 8.6 does not support DAQCard devices, I have been suggested by italian NI technical support team to use DAQmx 8.3.1 which is the last version that with VISTA DAQCard devices are supported.
Everything works fine but the board serial number is not correctly recognized: NI-MAX reports 0x0 as serial number and of course when I use the library function to retrieve the serial number ( DAQmxGetDeviceAttribute ("Dev1", DAQmx_Dev_SerialNum, &sn, 0) ) I get the same result.

I found this problem only using VISTA: in Windows XP it works fine
This is a big problem because I link the software to detect the serial number in order to copy protect the software itself.

Do you have any suggestion?
Can I bypass DAQmx control and directly access to the register-level serial number information I need?
Is there an another unique information I can use insted of the serial number?

Thanks in advance

Hi pejo1964,

DAQmx 8.3.1 drivers are not ufficially supported by Windows Vista, so it is possible that you cannot use the whole funcionality of the driver..

I verified that the minimum version of DAQmx supported by Windows Vista are DAQmx 8.5 as stated in this document, and it also supports your DAQcard 6036E:

Try to install these drivers and see if everything works fine.
